Guys this is not the International / Interlux
paints we know in the marine industry!
This
paint site has some buggy invisible code that does not allow links to be created or this sites hyperlinking feature is broken?
First any finish that you don't buy from a reputable marine supplier is most likely NOT going to hold up. Second any "varnish" that says two to three coats clearly knows nothing about the marine environment. A properly applied
varnish begins with 8-10 coats, sanded in between, and the first couple of coats thinned down to as much as 50% for good pore penetration and bonding.
You can expect to pay between $25.00 & $70.00 for a a quart of quality marine
varnish. If it costs much less than $25.00 start reading labels and checking with the folks on the forums.
Even if it was a marine varnish and you applied two to three coats you'd barely get four to 5 months out of it. Cetol & some of the more expensive two part varnishes are about the only products that you can get away with three coats but they are not a traditional varnish..
