Hey all,

Just a heads up Humbrol are taking note of the problems that some have been experiencing with Humbrol Clear frosting up once dry. This is a problem I have experienced to a serious degree with my Comet Racer GB build ruining the model (see here).

I contacted Humbrol over a month ago and heard nothing back (unusual for Airfix/Humbrol support) I must admit I was pretty miffed. I was pleasantly surprised to find out yesterday evening that Humbrol have been running tests on the product. They are asking for reports of instances of the frosting via their Facebook page. For those without Facebook I urge you to email them with the conditions under which the product was used (brushed/air brushed, over what paints, temperature at the time, etc).

Humbrol currently think that it is when the product is exposed to temperatures of below 10 degrees Celsius. However from my own experience I know that this was not the case with my model being in our living room which rarely falls below ten unless it's very cold outside.

If anyone else has had this problem don't suffer in silence contact Humbrol as the only way they are going to be able to fix the issue is with as much information about it as possible.

I don't use it myself, but honesty like this from a company can only be a good thing, well done Humbrol :thumb:

The problem that I have with it is that it won`t dry properly.
It`s still slightly tacky days after application.

I contacted Humbrol a last month to discuss the problems having seen a few cases (including yours) on here and elsewhere. It was only when I sent a list of all the cases I knew about that it was obvious there was a problem that needed investigating, as previously the customer care contact had only logged a few complaints. Humbrol have jumped right onto it and are investigating the problem to try to deal with it.

The moral of the story, if you have a problem let the company know directly, otherwise they won't realise there is a problem!
So if you have had issues and don't Facebook use the customercare@hornby.com e-mail to give your feedback.

I'm actual glad to read this thread about possible issues with "Clear" I have experienced some interesting results myself and put it down to me contaminating the surface or something. I generally use Tamiya paints, if i thin them i use Revell colour mix. I have had one model have white patches appear on parts after use of Clear. the biggest issue was on a Armour kit i was making. I had finished the basic painting and sealed it with a coat of Clear. I then applied the Decals. I decided to coat if with a coat of Humbrol Matt coat next before any weathering. I left the model over night to dry. On returning to the model the next day parts of the paint work had completely dissolved exposing the primmer below.

I also have to say I've used Clear to seal 5-6 models without any complications. i currently have a Airfix vought kingfisher painted with Tamiya paints and coated with Clear on my bench now and have no bad issues.

I am however going to experiment to see if Clear and Matt coat react again on some old plastic.

I have issues with long dring time and it drying white splotches. I would say it dried at some where between 15to20 degrees

I've just squirted Clear all over the mid-stone paint on my Hurricane as a sealing coat before masking up for the dark earth camo, so far no problems. My experience with bloom (pale or white patches) is that it's usually down to humidity. If you're working in conditions of high humidity (which is often the case with modern homes), then bloom is always a possibility and some media may be more susceptible than others.

I have seen it mentioned on a couple of other sites that clear just doesn't like Tamiya paints. Is there any truth to this?

Well you'd have to ask the people who've had problems really :think:

Latest update from Humbrol;

Quote:
We are still testing on this product. At the moment it appears clouding can occur if there is humidity in the equation. If it is applied in very humid conditions or the kit is moved somewhere else to dry and moisture gets between the layers this clouding can occur. This is a notorious eventuality with this type of product and has always happened with others such as Johnsons Klear. As mentioned we are still testing on this product, however if you keep an eye on it as it dries and apply heat if there are any signs of areas clouding that would be the safest bet. Of course as we always recommend please test on a spare piece of sprue before applying to your actual model. To be continued .....

I had this occur the other day when placing Clear over Humbrol Metallic Silver, I've just gently scrapped it off.

I've had similar problems with fogging with Clear, particularly when airbrushing it on. I'm now fairly convinced it's down to too cold a temperature. I'm going to do some experiments over the next few days, some in my work room indoors (very warm and dry at the moment) , and some in the garage in the evening when cooler. I find it very annoying, as we put a lot of time and effort (and cost) into our hobby for it often to be marred at the end by a poor finish. Like a lot of people here, we often blame ourselves, either because we think of contamination or incompatible products.
I have had some very recent revelations associated to temperature with Humbrol rattle can consistency that I will post in the appropriate forum too.

Did anyone had any problem when mixing Clear with other (coloured) Humbrol enamels? I find it easier to achieve a good finish while airbrushing if I add about 30% of Clear to the basic colour...

Can't say I've tried that! Be interesting to know what effects that would produce.

Interesting... in the short time I've used Humbrol Clear, (about 6 models), it had seemed to be OK and I previously used Johnsons Klear floor polish for years with no problem at all. With my latest use of Humbrol Clear on a Revell M48A2/A2C (1/35scale) it has fogged creating a white-ish bloom under part of some of the decals. Same room in the house and apart from it being slightly cooler I wouldn't say the slight drop in temperature was a factor.. its certainly not cold. Luckily as an armour model the imperfections were aptly covered in some wash & weathering powders but this shouldn't happen and I would have been cross if it had been an aircraft where greater perfection is required... I just thought it was 'one of those things' and maybe I'd applied it too thickly over brush painted Humbrol 66 ... but I didn't think so then nor especially now after reading of the problems. The brush painted Humbrol Matt Cote that I completed the model with was fine and didn't cause any problems with the Clear. Having used Klear & Clear as a quick way to gloss the model before decals to reduce silvering I shall now go back to Humbrol Gloss Cote and wait the extra time for it to dry. I guess I'll just use Humbrol Clear for transparancies in the future as I don't want to risk such problems, particularly as the M48 was a review for SMMI. I guess if Humbrol has fixed the problem its still likely that we are buying 'old stock' off the shelves... let me know if its still an issue and Humbrol want to hear more problem stories as I see the first post on the subject was 2013.. thanks a lot,

Only had the white frosting issue once and it seemed to be because it was raining and humidity is not good for varnish I'm told, not had a problem since only spraying in good weather. However I just bought a bottle of Clear matt and it's a worry, it's white in the bottle and that's how it drys on a model, tried stirring the hell out of it but no change, anyone else have this issue?

This happened to me yesterday. I'd sprayed on one coat prior to applying the decals. I left it a day then sprayed a sealing coat on top.

I looked on in horror as the Revell 1/32 FW-190 F8 that I'd been working on for three months started turning white. I'd just been thinking how this was the best airbrush job I've ever done on a plane.

I tried another coat, which made it worse. In despair I hurried to the forums and read about cold weather affecting the stuff. It wasn't a particularly cold day but I did have the window open to aid drying. In the evening, I tried a third coat, applied with a brush, with the window closed, and with my desk lamp directly above the model.

Thank god it seems to have worked. I was using Tamiya paint by the way, so perhaps there's some truth in that rumour?

So don't panic guys! :yahoo:

I've just had a similar problem with fogging again. This time it is on a Revell Tornado GR1 with (literally!) hundreds of decals. I've used Set and Sol and had fogging occur where I was too liberal with aforementioned solutions. So I'm fairly convinced there has been a reaction with either one of these, probably the Sol, with the Clear. A few extra coats of Clear mitigated the problem, but not entirely. Anyone else corroborate?

Hi Dazman

I used bucketloads of microset on the FW-190 but the whitening patches were occuring randomly and not just where the decals were applied. I'm still convinced it's a temperature thing.
