Well, I was able to get the scallops cut out, and put down onto my test piece, and then painted. Overall, Im extremely happy w/ how it came out. Adding tape to the paper backing on the frisket paper made it a whole lot easier to trim the mask out. The first one I did, i had problems w/ the paper backing ripping, making it a lot harder to trim it out correctly.
So on the second one, I added some clear packing tape, and that helped a lot. It helped to hold it all together, which made the trimming a lot easier, but it also helped make it more rigid, so it didnt move around nearly as much either, which also made it a lot easier to cut out.
Here is a pic of what the test piece looks like right now.
I started off painting the styrene sheet w/ Duplicolor Victory Red, that way the base color would be nice & bright, and easy to see. The top color is Duplicolor Deep Jewel Green ( a very nice color I might add
).
Put down 2 coats of the green, and then let it dry for awhile. Once it was dry enough, I pulled the frisket mask off, and it came off pretty easily. One pulled right off w/ no trouble, the other gave me a little trouble getting one corner up, but once it started coming off, it came up w/ no trouble. When I do the model, getting the frisket off should be pretty easy, as it will be right up against the front wheel openings, so I'll be able to get it loose there.
The biggest advantage of using the frisket paper, is also its biggest disadvantage, and that its so thin. When laying it down, it kinda wanted to go every which way. When it comes time to mask the car, Im going to have to use a ruler or something, to make sure that I get the lines all aligned correctly, b/c I know the frisket isnt rigid enough to go down straight enough w/o some measuring & tweaking.
But, I have to say that this is most definitely very possible using this method, and something that I would probably have to recommend to others for masking off difficult paint schemes.
