I am considering (if the budget will stretch) painting the topsides (not the deck) with either the new 2-part poly from Interlux (Perfection - replaced Interthane) or with Sterling. They are both in the 240 per gallon range - Sterling may be a bit more than the Interlux product. I have seen results of a Sterling application. It looked great! But it is more expensive and more fussy than Prefection. Perfection comes in quarts with both parts pre-measured and ready to mix. Sterling comes in gallons, requires more mixing and more thining. Has anyone used (or even seen) the results of Interlux Perfection? I am would love to know how it worked out.

No personal experience with those

but my former neighbor in Seattle had painted his topsides with the regular one part Interlux paint and it looked like it was sprayed on at a factory. He used a small amount (about 5% ) of Penetrol and used the roll and tip method. I think that there may be more info on that in the archives but I don't know for sure. You might want to run some tests before you spend so much. Good luck.

Two-part Good Choice

If you're seeking perfection the two-part product is a good choice based on my experience with Interlux Brightsides. With regard to Brightsides, a "one-part" product, I followed the directions exactly, including downloading the more extended directions from Interlus (recommended), talking to yard personnel who were well versed in use of the product, as well as the manufacturers rep, and the finish was less "smooth" than I had hoped for. This is kinda like saying I'm not happy. For the cost of the product and the time + effort involved, the few extra bucks for a two-part, personal opinion, is money well spent if you're seeking perfection.

Ive brush applied and also sprayed Interlux 2-part

paints with 'dazzling' success. I'd recommend Interlux Interthane but havent used their Perfection series (yet). For any two part paint the solvent to base mixtures are VERY important to obtain a flat finish. There is a 'landmark' article written by Don Casey for the proper mixtures using a flat glass plate and carefully mixing the thinner that will usually result in a finish that rivals a spray job. www.sailnet.com/collections/articles/index.cfm?articleid=caseyd008 (article title: "New shine for old hull") With this method of Dan Casey's I can produce a 'perfection' finish that is just a 'wee bit below' that of a spray job - but it takes THREE people to do it: one to roll, one to tip, and one to keep the paint stirred. I'd avoid the 'single part' paints as they dont last as long and usually begin to 'chalk-up' / dull in a few years. Go with the 2-part: Interthane, Perfection, etc. The stuff is impervious to the elements. Caution: with **ALL** boat paints, you cant cover the boat with a tarp once you paint the topsides and deck ..... without very special 'venting' precautions. The humidity trapped under such a tarp (and no matter how well you 'vent') will/can 'lift' the paint. Hope this helps. ;-)
