Ok some more questions. I went to Lowes today and looked at their rustoleum. It says to thin with acetone and that mineral spirits is not even an ingredient in their paints. However I went to Tractor Supply Co. TSC and looked at their valspar rust preventative enamel and it says that mineral spirits is the main ingredient of their paint. However, Valspar can says not to thin at all? Can I use the valspar paint and thin it with mineral spirits? It is enamel after all? I am starting to think that tremclad is not the exact same composition as rustoleum.
