Peter, Conversion Varnishes are converted to plastic by the addition of an acid hardener. They are very hard and resist most chemical assaults such as nail polish remover (acetone). The are okay fillers on porous woods but I dont like them for filling larege holes or defects. If you use them to fill open woods you must sand down almost back to the wood after applying 2 coats then apply 1 or two even finish coats properly reduced for flowout. Sherwin Williams makes a good one called "Sherwood". Aloha, Mike Gagne: Although I have done a lot of finishing I dont know the different finishes chemically, just how they preform.: My experience with conversion varnish is that it is a high build, high solids varnish that can be hardened further with the addition of a catalyst. It is designed to be sprayed and a few coats build up quickly. One of the things I really liked about it was because it is a high solids finish I could even use it to grain fill.: My suggestion is if you have a spray set up, get some and see what you think.: Sincerely: Darryl Keil: : : Darryl,: : You referred to "conversion varnish" in a previous reply. What exactly is this?: : Peter B.
