Isn't Testor's Dullcote a lacquer formulated spray coating and usually doesn't cause any plastic damage since it being sprayed over a previously applied paint?

Its been 20 years since I use a can It may be laquer ,
I check some of my old stock , and "Clear Cote" is laquer and the Testors paint cans say enamel. And now that I think about it I think I did have problems with "Dull Cote" if was spayed to thick .
Floquil you had to put an primer coat on plastic. Most just spayed it on lightly so that its almost cured when it hit the surface.
Enamels tend to have high viscosity ( thicker and slower flow) Lacquer is usually low viscosity (fast flow ,thinner) .Lacquer usally uses xylene , what Floquil called Dio Sol for the solvent/thinner because it has a low viscosity/surface tension to make the paint flow and atomize better (smaller droplets) .
Most paints are supposed to have less than 2.5 % ? solvent to meet EPA low VOC standards,
Bottom Line : if its Laquer based you test it first to see how "active" it is . Especially if you have a lot of time invested in the model.
Hold the phone guess what I just found , I have a can of Rustoleam Matte Finish I purchased to coat a custom lettered keyboard , I spayed it on some Styrofoam and it chewed up pretty good , will post pics later. Must eat now.
