We used this company 3 years ago to repaint all our exterior windows, front porch and deck rails. Within 3 months, the paint started coming off in several areas. The company did come back out 4 times in an attempt to fix the problem but it continued to chip off in many more spots as well as the original ones. We ended up having to hire a painting company to repaint the entire house 8 months after spending a "fortune" on this product.
Its been almost 2 years since the repainting (using regular paint) without any problems.
