Makes sense, thanks. I think I'll start out with 1500. Even if it takes a little longer it would eliminate a whole step with 1000 or 1200? 1500 then med compound then finish compound (Finess it) ? is that the stuff? This is a ways off anyway, got the transom and floor to deal with first. Finally got the engine mothballed and off the boat Wed night. Still need to build a cart / cradle. Don't see many pix of cradles on this forum. I guess just a rectangle out of 2x6's and then some struts up to stringers with wrapped with carpet? I thought of just leaving it on the trailer, pushes around easy but I think it would loose it's shape when the lid comes off. Maybe I could just put more struts and supports on the trailer? What do you guys have?
