Recently installed James Hardie siding on my home, needed flashing at every joint and these worked perfect, spray painted the same color of siding so they are not visible at all. Highly recommend

I was testing methods of decorative details on a lending library. It worked out okay, easy to nail through and bend. Didn’t end up using it for other reasons but it’s still a good buy.
