Also in
Florida and it is a demanding
environment for finishes that dry hard. staying ahead of the finish starting to crack becomes difficult for all but the most dedicated of boaters. And of course if it cracks the task becomes even more work.
I've used Starbright Teak Oil Sealer in the past with good results. Brings out the grain, good color and doesn't crack. Just wears away if not kept up.
After this I went grey for a couple of years. A
salt water washdown didn't work as well for me as some have experienced. The
wood has gone away, especially the soft grain, more than acceptable.
Six months ago I used La Tonkinois on all but the toe rail. Currently I am doing the toe rail and the biannual recoat on the rest. This may be my product choice going forward.
This product is a mix of oils and resins, not really a varnish. I has no solvents so it is not gassing out while using it and is not hard to tolerate. Smells good actually. No thinning the first coat required and only the first coat requires a light sanding to continue. From the second coat each coat goes on after a twenty for hour wait. So it becomes a daily routine for a week and a half or so and looks outstanding to my eye.
It does not dry hard so it expands and contracts with the wood and won't crack allegedly. After six months with eight coats this has been the case for me. It has a good glossy finish and good natural color. After six months of Florida sun it has
lost some gloss. But absent of cracks to redo it requires a light sanding and add a couple of coats. If scuffed or damaged it can be spot sanded to feather and spot repaired, though I have not had to test this out yet.
My hope is after a couple of seasons with no cracking it will build up to a smooth deep finish with only a light surface sanding and
maintenance coat each spring and fall.
