I've been in the paint wholesale/manufacturing business for 11 years now, so I may be able to help. Here's the deal on paint, be it marine, automotive, industrial, or house paint. It's always better to paint on a vertical surface. Reason being, it doesn't give the paint a chance to pool in areas that are lower then the rest of the surface. When this pooling happens your paint film is much thicker than anywhere esle and all the evaporatives in the paint have real troubles escaping and ensuring a proper dried film. It takes longer for the paint to dry and it won't dry nearly as hard if you were to do thinner coats. The golden rule is 2-3 thin coats of paint is better than one thick coat. Plus it depends how your painting it. From what I've read that Steelflex is quite thick and shouldn't be a horrible problem in running. Just invest in a decent "china bristle brush" or natural fibered brush from your local hardware or box store. The cheaper you go the more of a chance the bristles will come out and stick in your paint. Mid line pricewise will do fine. Plus it's on the bottom of your boat only the fish will notice. :mrgreen:
