Combo Man & Mod
I have been using epoxy as a surfacer on some of my jobs. This is, so far, an "off label" usage. As far as I know, SPI has not done any testing on the long-term durability of high epoxy film builds.
I have some jobs with 4-5 primer sessions of two coats, each 2 to 7 days apart. They are blocked out in between, but some low spots are holding most of the primer. Conceivably there could be close to 10 coats of primer in some areas, usually in factory waves near edges of panels, though we always sand off the excess right on the edges to increase chip resistance.
Has anyone experienced problems with high film builds?
Barry, if there was to be a problem, what would we look for? Do you think it could crack in a few years?
