this stuff worked great!
After much review I decided to purchase RV Roof Coating for a metal roof which has seams every 4 feet. First do not use this coating without first applying the primer of same brand. Primer provides good sticky surface for primer.I applied two coats allowing good drying time in between coats. Since finishing project two heavy rain storms have hit my area. Proud to report no leaks or problems. I highly recommend this product for sealing a leaking roof of prescribed material.
