I have a 70 model camaro,and I'm using epoxy sealer/primer, what i was wondering is what is the best way to get it to the metal? I used a electric type sander,and for about 4 hours,and I almost got the roof done,and that is it. it gets overwhelming sometimes,especially when you are trying to go to super chevy,and the back half isn't done the front is done,but everything is also new,and I have sealed all of it.There is alot of little places I cant get to with sand paper,any ideas. I seen some sand blasting,but its suppose to be bad on the panels not sure,and its probably extremely high.Did i do the right thing going with this type of sealer?Could I use a chemical stripper what would be best?
