| Hi ldf33:
I use modelmaster enamel primer. Its expensive but is very specific to plastic. I apply only to medium to large parts-I thing small parts are not worth the airbrushing. Primer binds the paint to surface and prevents the top coat from chipping, especially on frames, ect. OR use very light coats of the matt black paint to cover the area but if priming through an airbrush in light mists-I can usually put on the top coat very quickly. I've used off the shelf auto primer as well with mixed results and needs to be tested before use on a spart piece of sprue from the kit with the glue used on the construction first. Hope this helps, Jeff |
