I had a body guy helpin me, said about the same, just a real hard thing to do workin in the back yard mostly by yourself, even the panel painting was recomended against, but there's no way I could prep a whole car & get it painted up all at once. took all day just for the rear of the shell(exterior) interior was done & sealed off, same for the eng bay.
So far the panel painting hasn't bitten me, the chips, I expect more, specially when I do the header & the valences, guess it's too late now, but I'm takin notes, texas cuda will get a different approach!
The learning process is tough on us sometimes, but the deeper the cut the more careful you'll be next time!
& believe me I've blead some on this baby!
