Toluene and a scotchbrite pad goes a long way.

For recoat, sand with 80 grit, toluene 3 times with 5 min evaporation between coats, then recoat.

Sanding is a required step with hypalon to promote adhesion...be it glue or paint. The sanding does not need to be deep or prolonged, it simply need to be enough to scuff the top smooth layer off the hypalon and cause some "jagged edges" in the material.

Barnacles will do 10x more damage than the sanding will. Bottom paint your boat annually! I recommend utilizing a flexible bottom paint. Pettit Hydrocoat SR is my favorite. It is water based, low-odor, and can be removed easily if a repair is required.

The boat is going to be kept on a trailer. The only reason i want to re antifoul is that the previous owner kept it on a mooring and has previously had it antifouled. This is now flaking off and i just want to tidy it up and make it look all shiny and new for my own benefit if nothing else!!

I am in the same position re anti foul and boat now to be kept trailered. My plan is to remove the old with anti foul remover and try and clean the hull up to improve the looks (sad I know). The downside is I won't know how badly the hill was key'd prior to application.
Has anyone done this before with success ? Any tips ?
Cheers
Paul
