I just did a 30 day test on a finish from Fiberlay distributors...called Insignia. It is a linear polyurethane and it had Zero problems. Less expensive than Signature.

Connor they have a shop in Sarasota, off Clark and Lawton.

It took a while, but after 31 days in the Bahamas in summer, here is the answer for original gelcoat.

two weeks: no problem, no significant sign of fouling.

2.5 weeks: here it comes, light scrub took care of it

3.2 weeks: scrub again, harder, worse at the water line.

3.8 weeks scrub again, lots of algae, well stuck, no barnacles.

It worked, but I'd rather not try 6 weeks.

Connor,

I don't know if the growth is the same in Nova Scotia and I'm sure it's not if it's different in Fla. and The Bahamas. I made the mistake of leaving my 17' seaswirl (no bottom paint) in last year for a couple months. I power washed all the hair and most of the barnacles off, which left a black/yellow colour. My buddy gave me some stuff that you just spray on and it pretty much washed the rest off with minimal scrubbing. Unfortunately I can't remember what it's called but I have some in my garage. Next time I'm in N.S. I'll have a look and report back. I still had to scrape parts of barnacles off with a putty knife.

Hey Connor,

That hull cleaner is made by a company in Dartmouth N.S. called Bebbington Industries. It's simply called hull cleaner. My buddy got it at our local supplier for the local lobster fisherman. He is a dealer for Stright-MacKay.com It's on page 452 of their catalogue.

If you can't get this in the States, or order it from Stright MacKay, I'd be happy to send you some.
