The old saying was, I think, that you could put anything over Aero Gloss but you can't put Aero Gloss over anything else. Or something to that effect. I read in a magazine once where some one had their thinner analyzed and found that it had 14 different solvents in it. If you have some old thinner it's great for cleaning brushes!  Testing on a sample is the SOP for this.

   I have accumulated a lot of old stuff over the years and have provided Aero Gloss to guys restoring older models and needing original stuff for the compatibility issue. I'm working in my garage clearing out and cleaning up and will see what I have in black. I'll get back to you ASAP.

I have some over 50-year old Aero Gloss in several colors.  It still works great and is almost as fuel proof as epoxy.

I've thinned it with regular Home Depot lacquer thinner with no problems. 

Back in the day I could do a multi-color Aero Gloss paint job with a brush.  No problem.  The base color did not soften & mix with the later colors.  You can't do that with Randolph or Brodak dope.  That forced me into air brushing.

Aero Gloss was about the only finishing product any of the gang in my home town used.  Way back in the 60s it was in every hobby shop and the last time I used it was in the 70s.  It had pretty good fuel resistance, from what I remember.  Much better fuel resistance than today's dope.

I wonder if Aero Gloss was truly dope.  That is, of the same chemical formulation of butyrate dope.  Today's butyrate products have such little fuel resistance it is quite a stretch to call them fuel proof.  I wonder if the EPA had anything to do with this.  Making a product more environmentally friendly might have resulted in less fuel resistance.
