I have opti-coated my roof 2 times now and it never stays. It seems to wash off and not bead the next wash.
Quick background: I re-cleared one of my fenders. Didnt mask off roof at first. Overspray travelled over over roof. I then layed plastic over it to prevent more from travelling over the roof. It has since sat for around 6 months until I decided to opti-coat my car. My roofs clearcoat is beginning to fail. So I wanted to opticoat to try and stop it.
I initially polished and clayed. Applied, opti-coat didnt stick. Thought it might be because I did not remove all the M205 and it caused it to not bond. I lightly polished the roof. Did all the IPA, OPC crap and applied again. Still no luck, the OC will not bond.
I thought back and remembered clear coating my fender. Talked to chris and he said that it could likely be the problem as OC will not bond to an unclean/non smooth surface. I did the baggy test today and my roof failed miserably..
So I am thinking that all along, it was the overspray that is the problem.
Okay. So the issue I am having now is I cannot get all the overspray off. I am using my most aggressive purple clay. I cannot hear or feel any catching or grinding like you do with normal fallout removal. The clay is simply gliding over the surface, and since the clear coat is clear, I cannot see any contaminents on the clay..
So I did the baggy test after claying, it felt a little smoother, but not by much. I then went at it a second time, and put around 5-10lbs of pressure and passion on the clay and went at it again overlapping many many times. Again, it feels a little better, but some spots are still very rough feeling through the baggy.
Geeks, do I need to just keep claying until its all gone? I mean, I am going over the same spots probably 20 times.
This stuff is really quite stuck to the paint. Luckily I am not instill any marring from claying so aggressively. But I am just not seeing a big improvement like when you normally clay a car.
How should I continue? I need this overspray gone so I can coat my roof.
