temp paint...

Are you gonna pull all the glass over the weekend??? Where are the rust problems?? If you pull the fenders off over the weekend and put them back on, they will need to be pulled again to take off the doors. Do you want to do all the jams, core support, engine compartment, interior, door handles, trim??

I would do the car at one time pull all the trim, door handles, glass etc....deal with all the rust and dents (hammer/dolly), sand the old paint down (or remove it), use DP90 epoxy primer. Do your filler work, gaps on doors/fender/hood and then hi-build primer.

Problems being rust.....you may find a bunch hidden under that paint, then panel replacement and patch panel work. Or terrible prior work.......license plate for patch panel type stuff

Oh yeah.....if you use base/clear, you cant wait to do the clear. The clear seals the paint
