Folks,

I painted the hull with two part Interlux Perfection, tech specs said basically 3 days was the limit to leave it in the water. No kidding! I left the boat in for 5 days. My mistake! Barnicles started to grow on the stern and I got a few small bubbles in the paint. Water temp was way up at 90.

I won't be doing that again. No damage to fix, just mad at myself for not paying attention.

Peace.

Ed.

I'm curious and wondering why you would use something that only lets you keep it in the water for 3 days at a time. Is it supposed to be used on hulls underwater? Also, how long do you have to keep it out of the water before you can put it back in for it's next 3 day immersion? I've never heard of anything like this and it would seem to be a collossal hindrance to using your boat. Sam

samsam,

This is really an issue of keeping the stuff from growing on it, normally, I would lift it back up on the davits or trailer it out, had it at my neighbors dock, for convenience, while I had guests in town.

Down here you really need an anti-fouling bottom paint if you plan on keeping it in the water.

When I talked to the tech guys at Interlux, this was their recommendation for trailered boats. One of their first questions was will you be keeping it in the water. Also if you use anti-fouling and then trailer you can wear the paint off pretty easily.

As far as time out of the water, it is more related to keeping the hull clean and getting the little critters off of it before they get a good hold. Very warm still salt water, like the canal across the street make for very fast growing barnicles. Once I pulled the boat out let it dry, and cleaned it, it can go back in again. I have been dropping it in for weekends with no problem, just let it go a little long this time.

Peace.

Ed.

Bond-o,

So are you saying run of the mill rustolium will last 4 months without anything growing on it?

Right now gulf temp around 89, lot's of critters growing on everything.

Here is what is growing, just on the transom, rest of the hull is pretty clean.

Ed, I had thought that a two-part polyurethane paint would be suitable for below the waterline usage, yet you still got blisters. I couldn't find an advertisement for "Perfection" to see if it is a "below the waterline paint", however.

My speedboat is painted with Awlgrip (Two-part poly paint). The parts of the hull that are underwater (ie above the bottom paint, but below the true waterline) have not blistered in 5-6 years of saltwater storage. Heck, the entire boat was underwater (sunk) for a week without blistering.:^

Chris,

Below is the URL For the tech sheet, it specifically says for use above the water line, I sent an e-mail to tech support before I used the paint and they told me it would be OK below the waterline, but only for up to three days. In my case the only areas effected were immersed in water, which I know is a no no, but there I go being human again. Lesson learned, bottom paint for immersed sections of the hull if I plan on leaving it in the water. Like you said parts of the hull above the true waterline were unaffected.

In retrospect I got more advise from some builder friends who echo what you are saying, Awlgrip is "the choice"!

Peace.

That almost looks like an STD! :% At 5 days, it takes about the same time, too! :/ Somebody needs to invent an anti-fouling wax. Sam

samsam,

Ouch! I don't think I can ride in the boat with that thought in my head. Will be ridding the STD today.

Peace.
