so, i created a wrinkle or bump on my roof panel when applying my filon today. i used contact cement, so when it stuck, i was done. is there a good option to fix this? my only thought is to make a linear cut the length of the wrinkle. let the 2 pieces relax. then cut through both over lapped pieces to create a new seam. then caulk or seal over that seam. any thoughts?
