Re: inflatable with coat of epoxy paint on the bottom ?
Is that a rib or sib inflatable. If it's just a epoxy coat can't see how it could protect inflatable underneath, it's just a thin coat. There are special products for painting inflatables, which should be flexibe as not to be peeled off. Probably had to much scratched bottom, painted it to sell it in much better looking condition, as everything comes through the eyes..
