I have used clear base paint (no tint) on a couple of occasions based on the recommendations of others and readings on the net. However, I’m still uncertain how long I can expect it to hold up out in the sun and weather. I have just spent some time looking through old postings about this on this forum and most, if they say anything about it, don’t report any results beyond about a year. Does anyone have results beyond that?

This past spring I “painted” a pine board with 3 coats of SW A100 deep base and laid it up on my roof in a place where will get maximum sun and rain. After only 2-3 months, it looks fine as you would expect. I’ll report back periodically and let you know how it is doing. Maybe someone else has already done something like this.

Correction:
Oops! sorry. Not SW A100. It is SW oil base All Surface deep base.

I used a clear base on some deck chairs a few years back. We lived in Las Vegas at the time and the chairs were by the pool. Maximum sun exposure to intense sun and heat. The finish lasted about 3 years before it started to peal. I seem to recall it was the SW medium base.

I think any test results are so unique they may not apply to everyone. In the mountains thew results may be entirely different than if you lived in the woods. It might also vary with numerous other differences, like brand, etc. I’ve used it a lot (only Olympic oil based and SW A100) , and for the money it’s as good as any clear coat you can apply. But it will need maintenance eventually, they all do.

Fred makes a good point. Having lived at sea level and at elevation (Vegas is about 3000’ and I’m currently at about 5200’) the differences in UV are dramatic. The lack of humidity in the Mohave and in the high plains really impacts the filtering effects of the atmosphere.

Do you think that it would be a benefit if a number of posters from different parts of the country and from differing environments did a similar long term test and reported the results back to the forum?

Sure, but they all need to do the same thing – same wood, prepped the same, include the same multiple finishes, applied the same way, the list goes on. Without proper controls its not really a test.

There is enough information in my original post to do an interesting and informative comparison even if it might not be classed as a true scientific test. I’d be happy to provide any other info needed to make the “test” more credible.

Have your say...
