Bottom paint. -

I hope this is the correct forum, if not I apologize.

I have a bottom paint question.

I have never owened a boat long enough to have to repaint the bottom, but this one I intend on keeping for several years and would like to do it right.

I just hauled the boat for the season and power washed the bottom. It has flaked pretty good. I was able to powerwash the bottom good enough to to flake off a good portion of the bottom.

With that being said the bottom has had a barrier coat application applied to it, I just do not believe the anitfouling paint was applied in the correct timing sequence as it does not appear to be sticking at all.

I plan to take the rest of the anti fouling paint off this weekend, then sand the barrier coat over once to rough it up.

This is where my questions lie.

1.How much of the barrier coat should I sand down?
2. What type of barrier coat product should I use to prime "over" the existing barrier coat?
3. I have currently purchased 2 gallons of Petit Hydrocoat- what brand primer will be compatable with the petit anti fouling paint?
4. Is there a crucial time line from applying the primer to the anti-fouling, beyond the recomendations?
5. Is there a crucial tempature to be above, other than the recommended temp when applying the materials?

Thanks

You dont want to sand it just scuff lightly with 200 grit or so until there is no gloss. a good wipe down with acetone or lacquer thinner before and after sanding might be in order because somebody did something wrong otherwise the paint would be sticking better..
