One more time CPES

[Steve Smith]

Thank you, Cliff; you may certainly ask. Clear Penetrating Epoxy Sealer is not intended to be resistant to the ultraviolet of sunlight, and indeed it is not.

Here is an article I wrote that explains the underlying science of clear finishes: How and why they fail, and why they can last for some length of time: http://www.fiveyearclear.com/CCOW.html

The best commercially available varnish is Epifanes gloss, and I wrote an article about applying varnish: http://www.amateurboatbuilding.com/arti ... index.html which will help, where you may wish to use it.

That material is the most flexible of the varnishes, and thus will hold up to the ultraviolet of sunlight the longest, but also will have the lowest abrasion resistance. For clear-finished wood exteriors of trailers that will be on the road, and get wind/dust-erosion, you really need a two-part polyurethane. One of my distributors, Star, also handles a decent one, Bristol (the 2-part, not the waterborne version which is for interior use only): http://www.star-distributing.com/bristo ... lindex.htm.

The Bristol folks have been around a while, and they make a decent product. Usage should be budgeted at about 80 square feet per gallon net total usage. I'm not saying how many "coats" it takes, because there's no definition for the film thickness of a "coat". Using that much will give good UV protection and will stand up to most typical flotsam and jetsam thrown up in road-travel.

I bought the 2 qt. system of CPES and loved it. I put 2 coats on the front, top and rear, of my 5 x 9 tear then started a third but could tell it was not going to soak in. I had a little left over with the 2 qt. mix. I just purchased another 2 qt system for the next tear. Great stuff
