Rustoleum recommends their thinner 160402 to thin the epoxy for air atomized spraying, since they only sell it in gallons (Max thinning about 10%) I am looking for a smaller size of an equivalent thinner. Anybody sprayed the stuff without thinning it? It is for chassis parts and underbody parts.

Have a look at the MSDS sheet, looks like the primary solvent is Xylene. You will be safe to purchase and thin this epoxy mastic with Xylene. You can get this in quarts at a paint store or Home depot

Thanks that is what I was looking for.
