Hello all I was wondering if anybody has done or seen any tests comparing the durability of the various brands of spar varnishes? I have used products purchased from Marine supply places and they are about double the price that you would pay for what is sold at HD or a paint store. Am I getting that much better a product or just paying for something that says “marine grade”
Thanks
Troy

I suspect Practical Sailor has done such a test. Generally you get what you pay for. UV protection costs money; also you can't skimp on the number of coats you put on.
Many swear by using CPES (Clear Penetrating Epoxy Sealer by Smith & Company) as an undercoat for varnish. It's not cheap, and, as a friend says, "I can feel those brain cells dying." when she uses it.
Thanks I have used Smith & Co. products as well and have been pleased.Thanks
If there is any sunlight involved, the true marine products are cheaper than the junk you get at HD or ordinary paint stores because they are likely to last more than two times as long. Ed's Smith & Co. CPES suggestion is a good one, but remember that it still has to have the good spar varnish over it.
There are three brands that stand at the top. Epifanes, with its traditional Gloss, Interlux Schooner, and Pettit Captain's. These generally come out near the to of the Practical Sailor tests and also the yachting market place. They are worth the money. Follow the manufacturer's instructions, although you may need to add a bit more thinner, especially with Epifanes, than the label calls for. Also note that the instructions to use 6 or more coats is for longevity, not just to get the marine "brightwork" look.
Even with the best regular maintenance of clear finishes that see lots of sun is required. In full sun (as on a boat) expect to lightly sand and add a maintenance coat annually, except in the South, where that can become a twice a year task. You may be able to skip a year occasionally with the CPES underneath.
Check out http://www.defender.com for good prices on these marine finishes.
Thanks for the reply I have used west marines varnish that is made by Epifanes and was pleased with the results. I will look up the magazine you suggested for more info. Most of what I hear is opinion and anecdotal although I am sure you get what you pay for.ThanksTroy
