Vinyl Top Installer Western PA

I used some 3M contact that we had at work. It wasn't the super yellow stuff but I saw it recommended at a few places. The roof was primed and had some overspray on it from the whole body paint job. I scuffed it with 220 then glued the vinyl on. The vinyl came from Dante's. I don't think I stretched it enough and it wasn't hot enough in my garage.
