Weathering

I bought an air brush a few years ago but have yet to try it. My prodjects are usually small. I've never had a problem with Testors. I've heard people complain about the price but not the product. It's great for sealing your work and hiding decal lines.

Any recommendations on an AiRBRUSH final dull coat for rolling stock?    I recall reading  Testors  had issues.    

In fact, Testors Dullcote is the one -without- issues. The hardware store matte finishes can bite you - though some do and some don't. Dullcote is still the "flattest" in my experience.

A compatibility test spray is always a good idea, regardless of brand.

I still use and recommend Testor’s Dullcoat. Before and after weathering this covered hopper. I use chalks, and sometimes need to re-apply the chalk as Dullcoat tone’s  down the chalk.

I have used Testors dull coat plenty of times without issues. It is a lacquer and goes over just about anything.

I too have mostly used Testors Dull Coat in the past without issues.  One time I used a Krylon product and found it was not compatible with Microscale Decals.

Krylon has a base that is not compatible with many other paint types. It will craze many other paints, I only use Krylon on Krylon and it must be fully cured when topcoating or you will have issues.
