I bought some paint that was on clearance at TSC yesterday to try out my new air compressor and paint gun that my girlfriend got me for my birthday. The paint is Valspar Anti Rust gloss oil based enamel. I know that the other paints sold at TSC (BPS) is also made by Valspar. On those paints, it is recommended for spraying to thin with Naptha thinner.
On this anti rust oil based enamel paint, on the back of the can, it says do not thin. Does this mean that this paint can not be used in a spayer? Or is it okay to go ahead and use Naptha just like the other Alkyd enamel paints? It seems from reading the ingredients that it is the same type paint as their tractor and implement enamels. Any advice would be appreciated.
