I have brush painted over klear with no ill effect, but it is worth testing first.

It's easiest to use thin strips of masking to conform to curves without wrinkling. Once it's down you can use extra pieces of tape or masking fluid to increase the coverage. To achieve a proper circle the masking really needs to be cut into an arc shaped strip. It may take one or two attempts, but it is not that difficult to do this by cutting freehand, although it's a lot easier if you have templates to work with.

The thinner (as in width) the tape the easier it is to make it stretch around a curve to keep a straight line. Then once that is done, add wider tape to the side to be masked
I would always if possible use a single piece of tape. If you take a long piece - quite a bit longer then you need, then you can hold it out from the part to be masked and then draw it round in a circular motion and that will maintain the shape you need as it makes contact with the plastic.
Harder to describe then to do :)
This method works when working on masking off 1:1 (real size) car panels for paint :D

Interesting - even on a simple and easily accessible surface, I always find it impossible to get one piece of tape, however narrow, to go round a cone without totally losing the line. With 2 pieces, however, it seems to go right much easier - and the ends line up with no trouble. I wonder why that is?

Another way is to cut a circle of the correct size out of some masking tape or paper and poke the nose through. I've used this method a couple of times on models where tape is too fiddly.

Just a delayed thanks for all the tips here! I used small strips of masking tape cut to a curve and it worked pretty well. I'll post some pics soon when I get around to it!

I am going to attempt the demarcation line on a Canberra B(I)8, does anyone have any tips on getting a nice clean curve with masking tape? I have an idea of how I might try it, but if anyone's does it an got good results....... Please share your knowledge!

The demarcation line I an particularly on about is the line from the tail planes to the back of the wing.

I have previously made a paper template of the wavy line, then put a suitable length of masking tape on a cutting matt, then place the template down the centre of the tape and use a pen to draw the wavy line following the template, using a sharp blade cut along the line...and as if by magic two wavy demarcation lines, one for each side.

Hope this is of some use to you :thumb:

Hi all... completely agree... Tamiya Tape is the Duck's Nuts...
Two things that have rocked my masking world :

.04mm Masking tape Sorry can't remember the Brand:
Image

And a set of Hollow punches :
Image
These are an imperial set as the shop I went to didn't have a metric set, but at $20 bucks a set I'll get a metric set when I can find them as well ...THEY WERE A GAME CHANGER WHEN IT CAME TO MASKING CIRCLES and would be ideal for masking wheel centres

The .004 mm tape is ideal for masking complex curves. I used it on the Junkers F13 and gentley hand brushed the black up to the line :
Image
Image

And the Hollow punches allowed me to mask circles like the ball turret detail on the 1/72 Craftmaster version of a " A Bit O Lace " I've just started ...I could never have achieved the mask without the punches :

Image

I sprayed the mask on the Junkers with Tamiya Clear Gloss after painting and got nice sharp lines even on a corrugated service, But because Tamiya Clear Gloss does not agree with the Chrome paint I am using on the B17 I couldn't apply it to the Transparencies and the lines are not as sharp, as you can see from the photos...Still pretty happy with the results all the same.

Hope you find this helpful

:cheers:

.....Sorry forgot to mention the Tamiya Cutting board
Image[/url][url=https://flic.kr/p/PSyc8C[/img]

It has all these circles, radii and small squares and I'm only just realising what they are for. You can lay the masking tape over the circle, radii or shape and cut the tape to the desired shape... very handy on some of those tiny windows on the ball turret.
Tamiya also make a plastic aircraft stencil that has various circles, triangles,squares and Access panel shapes.

ok...I'll shut up now :Whistling:

:cheers:

I'm another wad punch user:

I bought a set of punches for about a tenner off the 'bay. You could buy the Maketar pre-cut circles set, but it's quite expensive, costs more than the punches in fact and it takes only a few seconds to punch out a dozen or more discs.
