Repairing and Repainting bottom of 20 ft CC

[ptruluck]

Need some help please,

I am have some farily deep gouges and scratches repaired on the bottom of my boat, plus old paint being scraped off.....

1. Going with 2 coats of anti-fouling paint (is that enough coats) and could you guys suggest best lasting brand - as will take on and off trailer alot. Want something that holds up. Boat would only be in water up to a week at a time max.

2. After repairs to the bottom, what sort of barrier coat or prep should be done before the two coats of anti-fouling paint?

I appreciate any and all advice....

Thank you
