I'm in SW Florida and I have used the Bristol Finish on the trailerboards - it self destructed. OK, I can live with that. What I hated was trying to get the remnants off
It's chemical resistant so stripper didn't work, it's heat resistant so a heat gun just scorched the wood. Its hard so I ended up using a much coarser sandpaper to finally get it off. NEVER MORE.
Epiphane doesn't work down here either. I had a beautiful finish and even told my friends about how easy it was to get a good finish. Three months later it was cracking and peeling. I did a web search and found that this was a common problem in the subtropics and tropics. Boy was I pissed after weeks of work.
Now I've gone back to the old tried and true. Z-spar Flagship. A little care is needed but it's holding up well.
