I've used it quite a while back. Personally, never again. I didn't think it lasted all that long and it is a SOB to strip. It's chemical resistant so strippers didn't work and it is heat resistant so a heat gun just scorched the wood. I ended up taking it off with coarse grit sandpaper.
What I use now is just good quality varnish
. My favorite is Z-spar Flagship. I'm coming up on two years and it still looks good. The trick, especially here in Florida
is to put down a lot of thin coats. Coats one and two are sealers, diluted with mineral spirits, the remaining coats are full strength although I put a touch of Penetrol in to keep down brush marks. By coat 5 its looking good but I put on a total of 9-10 coats with a light sanding
between coats. Those last 4-5 coats are what gives the finish the longevity IMO. Roughly once a year I give the brightwork a light sanding with 220 grit, and give it 2-3 coats. It's then good for another year. As you can see most of the work is in the initial prep and the application of 9-10 coats but thereafter you can coast. Also, I highly recommend the Jen PolyBrush available from either Ace Hardware
or Jamestown Distributors. I buy them a case at a time (48) to save money
. DO NOT use the cheap
from Lowes or Home Depot, they disintegrate.
This, at least, is what works best for me after experimenting for the last 14 years.
