STH , we had coated it with a good Poly , then a UV resistant coating … The Sun here is intense and the best we got was 10 years before it started to show wear and tear ( the sign) .. I think peeling is a result mostly of bad surface prep or incompatible finishes …
But then we’ve had good luck with good Exterior house paint … ( FS) The problem too is dirt ….. everything eventually gets dirty living outside , the FS is no exception , and a good twice a year wash down really helps … We’re still basically on our First paint job , but some areas have been re-painted as we modified it over the years … Still OK !!! I’m thinking about a repaint , color change soon … maybe !!!
Ps , here’s some signage we made for a local music store … 10 years outside facing West and a busy expressway … Acrylic paint with more poly /UV coatings… We also did the paintings of the rock stars , 4’X8’ each … I think they live in somebody’s garage now , along with that Big guitar sign .
