I have been having nothing but problems when it comes to wet sanding/buffing my hood. I have recently painted a fiberglass hood for my mustang and having had troubles with the sanding/buffing process before I made sure I did things different this time. I went straight to using 2500 grit (meguiars unitgrit paper) and had a steady constant flow of water over my sanding area to remove any objects which could scratch the finish which get dislodged in the sanding process. I go to buff the hood and once most of the small scratches go away, I notice a decent amount of large (several inch long) scractches which appear deeper. I end up having to buff for an extremely long amount of time (with Diamond Cut) in one area in order to get the scratches to go away. I spent over 5 minutes just a couple of the countless deep scratches. Several issues here:
1. Why did they get there in the first place, especially when using such a light grit of paper?
2. Why wont they buff out?
3. (Not related to sanding per-say) - Why when I buff, are there minute scratches (circular patern probably from the buffer) which won't come out either? There scratches are MUCH smaller than the ones described above. Im betting its from the buffing process, not sanding.
A little background - My hood was painted several months ago, its black and although I did not bake it, it has been sitting in the sun as the mustang is my daily driver. I understand that if you dont buff soon after painting that the process becomes extremely more difficult.
Buffing Process Im Using: Diamond Cut --> Fine Cut Cleaner --> Swirl Remover (Never make it to this step because of the scratches)
Should I just go lay a couple more layers of clear on the hood and buff it soon after painting?
Any help would be much appreciated - I've already invested 15 hours into buffing this hood and its no where near where it needs to be - it looks pretty bad.
Thank you very much - Ryan
