My autobody guys are suggesting that I clear coat my wood bed strips rather than coating them with 5 coats of valspar varnish. They say it is OK for UV and not to worry.
I don't know enough about clear coat to make an informed decision. I am a carpenter by trade and of course lean towards the Valspar although the clear coar seems awfully tempting.
Any suggestions?
I only want to do this once!
Thanks

Personally I would think the Valspar would be the better option simply because that's what it's designed for.
I would imagine clear coat while it would look good, wouldn't be anywhere near as hard wearing.
I'm not sure what your intentions are regarding the trucks use,but I imagine the Valspar would stand up better over time.JMO

UV protection is better, won't yellow as bad and just as durable.
Give me ambiguity
or give me something else

You can see it at http://www.mar-k.com/wood_finish_testing_ii.aspx Follow it through the 2010 update. Clear coats did not fair very well in the comparison. Probably because the finish is not made for a surface that can change as much as wood under different temperature and humidity conditions. Marine spar varnish did well.

If clear is used, make sure the ends have multiple coats before the other 4 surfaces are finished. As far as the clear on wood goes, we have been spraying wood and wood composite material for years and have never had a problem with the clear failing. As with everything-prep is the key!

If the coating cracks then it will start deteriating. "Spar" is the additive that is suppose to let it "move" and not crack.
...and as a former bolter taught me...let the boards stand in a pan of the sealer overnight to suck up all it can. If the ends get plenty it won't crack....cause once it does it'll turn black.
Good luck. | | |
