Rated 5 out of 5 by from Great product My go-to product for fairing, blisters and all kinds of minor repairs. Highly workable - spreads well, sands easily, doesn’t shrink. Only caution when working in open sunlight: cover it with primer soon after sanding. Like many epoxy products it deteriorates when exposed to direct sunlight.
