Re: 1976 22' Starcraft Islander Rebuild
Yep,
DougFir, HeartPine are just 2 of the woods that will darken as they age, and if you can find CLEAR (non-amber colored) Spar Urethane it will not deepen the red nearly as much as the varnish did, but the wood itself will continue to darken w/ either. The wood itself will change colors, darkening over time. Urethane & varnish will also start yellowing over time, even the clear (non-amber colored). Darker windows (curtains?) would help reduce those reactions. If you open the can of varnish/urethane and it has even the slightest yellow/amber hue to it, it will yellow over time. If it looks like a can of thick water, then it may not ever yellow.
If that lighter look is what you're trying to get, I'd recommend 2 coats of spar urethane (clear), followed by 2-4 coats of water-based urethane. It is completely clear (amber free) & doesn't yellow over time, at all. It can be sprayed/brushed (but I don't like to roll it w/ either foam or knap rollers), it dries really quick, and in quick application of a 2nd coat, doesn't require any re-prep. Drying quickly greatly helps it dry dust/bug free. :spider:
It does have a much longer cure time between dry to the touch & being cured enough for a light scuff before coats 3 & 4.
Of note, however, is water based poly doesn't have the same tactile feel of oil based spars or urethane, and the grain must be sealed w/ an oil based product 1st. Otherwise the grain will raise, and give unsatisfactory results....
