man, thanks for all the good info! i know i have a long way to go... and some info rather than down talk is appreciated! i have a lot of orange peel and some uneven areas due to a bad sanding job and im afraid that when i start sanding, im going to find some more bad areas that will need deeper repair. ive already found that in the 'rain track/gutter' as it was filled but not properly welded or prepped. not sure how i will fix that though.
