has anyone ever used a product called 'Bristal Finish'? it is billed as an alternative to varnish and that it has better UV protection than varnish. We are refinishing our teak cap rail and i am looking at the various options. A friend of ours had theirs refinished using Epiphanes using 7 coats here in Florida. After a 3 month trip to the Bahamas he came back with the finish deteriorated in a number of places. I know that typically varnish has to be reapplied every 6 months or so here in the tropics - but three months seems ridiculous.
