How Well Does TSP Degloss?

I've used TSP to bust the gloss on many a painted wall...but never on plastics. You might try starting with a very weak solution and then check the impact.

Actually, I think that I solved my problem.  I got a hold of Weaver and discussed my issue with the paint tech.  First, I do not have to degloss the paint before putting a primer or second coat on it.  After the discussion the choice was to put another black coat on it or prime it first.  In order to help whatever caused the blotches in the first place not to come through we decided it would be safest to prime.  I'll be using Tamiya paint to prime which is compatible with enamels and lacquers.

Thanks for your suggestion,

I use tamiya paint whenever possible. It is synthetic laquer but not harmful to other paints. It is the smoothest, best flowing spray can paint. Dries fast too. I would use Tamiya black too.

Thanks, Rob.  I agree.  After looking at my options I'm going to use Tamiya primer over the blotchy Scalecoat II.  I talked to the paint tech at Weaver and I do not need to degloss before recoating.  I have left over Scalecoat black gloss, but I think that I will finish the project with the Tamiya black.  It's a shame that their clear flat is no longer available.  I think that that may be a function of the EPA's doings.

Tamiya does still make a flat clear. It is TS-80. The semi gloss is TS-79.
