There are two ways you can do a paint job from bare metal.
1st- once the paint and bondo is removed either by midea or sandblasting down to bare metal you can go straight into the booth. Do not use any wax an grease cleaner or metal conditioners and make sure that no one touches the bare metal. The reason is because the metal has pours and any acids and other chemicals will not be able to come off the bare metal and when you shoot an epoxy primer on the whole car it will be traped and start to rust all over again. Just blow off all the dust and apply the epoxy primer. Then do all the repairs needed and reapply that same epoxy just before the primer surfacer then paint.
2nd-if you sand all the paint and bondo down to bare metal then you must clean/condition the metal with a metal cleaner and conditioner and apply an epoxy on the bare metal and then the primer surfacer for maximum corrosion protection. Or after sanding clean the metal with a wax and grease remover and apply an etch primer and the primer surfacer.
But the fastest way is the first way and the less work if you got the money to spend on the booth and blasting. I use PPG and Sikkens on a daily basis and both are great products.PPG makes an epoxy primer called Dp and you can apply bondo after one hour. If you're looking for quality and cost then I recommened PPG,But if cost is of no problem then by all means go with Sikkens thats my favorite.
