Have a 1/25 '70 Chevelle that will need a vinyl top. Are there any aftermarket kits? Masking tape painted? Other methods?

Masking tape is an option. Good quality tape, so it doesn't lift, when painted and wide enough, so you dont get to many seams.

Spray paint is another possibility. Spray short bursts, from a longer distance, then you usually would and wait until dry, between coats. Only add a little paint, with each layer, don't try to completely cover the model in a few coats. Keep adding layers until you've covered the model. This way you build up layers of spatter paint and eventually you will end up with a textured layer of paint, that will look very much like vinyl.

A vinyl top kit is another option. https://www.modelcargarage.com/eshop/pc/viewPrd.asp?idproduct=63

As Jesper said, spraying from a greater distance so the paint partly dries before it hits the surface and gives you a fine sandpaper effect is a good technique to learn. You can do this with the primer and then do any colour vinyl top over it. Just remember to get some fine half-round Evergreen to glue down for the join lines either side.



Old CD covers are great to practise on for broad areas, plastic spoons for curved surfaces, I've burned through dozens of them.

Looking forward to your progress reports.

Cheers, D

Thanks. I'll give the kit a try.
