I am wondering if anyone has ever tried an automotive finish on wood? My partner and I are looking for an extremely durable finish for an outside project, and I was wondering about a clear auto finish. It works great on cars, what about wood? The client doesn't care what the finish is, just as long as it doesn't have to be done more than once. It's for quarter sawn white oak.
From Paul Snyder, forum technical advisor:
Wood needs a lot of uv protection from the sun when it’s outside. Two years without maintenance (re-coating) is very good for a clear finish on wood - a year or less is typical.
My neighbor finished the clear redwood siding on his house with a clear 2 part catalyzed auto finish. Two years later, it was peeling off in strips. The same finish would have lasted 10 to 15 years on a car. I did a baltic birch chest which lasted about 3 years before the cracks looked really obvious.
