West Marine recommends using Pettit "Old Salem" general purpose brushing thinner at $32/quart
for use with it's CPP soft ablative bottom paint.
I just barely stretched a gallon last year to cover the bottom of my P28 and I would like to use just a little bit of thinner to ensure full coverage this upcoming season.
Is ordinary hardware store paint thinner o.k. for use with soft ablative bottom paint?
