Undercoating

Steve68 said

You can use 3M™ Body Schutz™ Rubberized Coating or RestoRick (http://www.restorick.com) sells an undercoating that looks like the original. We used RestoRick's on the interior and 3M under the car and fenders.

This is what I would use. I have also used SEM brand chip guard on the inside of quarters to give it that factory undercoated look.

The 3M rubberized also works well and is light weight. Its not as tuff as the factory tar undercoating though.


I would clean the are up real good, knock the heavy rust off with a red scotch brite pad and wipe the are down with a good pre paint prep solvent.
