    Posted: 21 Jun 2016 at 10:56pm
Ok I have a 2007  Boston Whaler Montauk that I stripped the last 9 years of paint off. Hull is clean with very few mark from sanding. Gel coat is in great shape. I plan to put 3-4 coats of interprotect 2000 on the hull. Do I need a primer like Primekote? Will clean with the wash before rolling and tipping the hull. I sanded it with 80 grit. Does it help finish to hit it again fast with 100 grit or something finer? Can I do one coat first to see any of the sanding marks easier and then fill them? It will be between 70-80* F. Can I do one coat every day with no sanding? I was reading about it here http://www.yachtpaintforum.com/interprotect-2000e-drying-time_topic999.html.  Any other tips are appreciated thanks.

No other primer is needed, put the IP2000 directly on your bare, clean, sanded hull.  You can do 1 coat first, fill/fair whatever then subsequent coats on any timeline you wish, sand or no sand between, but take care to apply your anti-foul soon after your last coat of IP2000 (hotcoat). Alternatively you can let the IP2000 harden up completely, lightly sand the entire hull then apply the anti-foul.

Thanks for the info. So anti-fouling goes on how long after, thumb print test or when tacky? Thanks.

At the ambient temps you mentioned you are working in you'll not want to wait too long but sticky is too soon. Depends somewhat on how much material you are applying, a thin coat of epoxy might be ready to overcoat with anti-foul in half an hour, a heavy build can take considerably longer to stiffen up. As soon as it stops being tacky you go.

Thanks for the info BoatNut. Are thinner coats better Roller and tip with a brush? I did a kayak I restored with 2 part Interlux Poly which I rolled and tipped. Would have com out nicer if there were no bugs or crap from trees. You have to look close to see the imperfections but I imagine what could have been. That stuff is real tough. The boat is used in NYC area in saltwater. How long does anti-fouling paint last a few seasons? I use the boat 2-3 times a week. What is the best anti-fouling paint? Thanks!

Won't work to roll & tip epoxy barrier coat primer, if ultimate smoothness is desired simply thin it down a bit with 2316n thinner so it flows and levels as you roll it.  Use a mini roller on a small boat like yours.  I assume you are wet slipping seasonally? From Interlux, Micron 66 is really good but might be overkill technology (& price) for your project.

Yes it is in the backyard at the floating docks. Not worried about price if it works well. I guess product literature  tells maximum amount of thinner? 3/8 nap roller or sponge roller?

Nap roller. M66 big feature is it repels growth on boats that rarely move, self polishing so to speak, not an important feature for you.  Ask around at local marina and boatyard to find out what is working well in your area.
