I was looking at that to, I am at 1 1/2" front and back, I was going to leave it until I drove the car to see if there was issue's if it doesn't rub I would leave it, it will help to keep it stronger. also I found an area in my center section where there was no fiberglass at all just gel coat so I have a bit fixing to do. If any one is doing up a show car it would be very advisable to let the body sit in the hot sun for a few days it will save you a lot of heart ache later with a spoiled paint job, I was able to find over 30 air bubbles traps in the gel coat one was over 1" in dia easy to fix stuff so long as you catch it while it's still in gel coat.
Cheers,
Grant
