Jammin'

Did the jambs on the '66 . . . which were covered in 40 years of over spray, nicks, scrapes and primer scale.
Knock it down with a purple scotch-brite . . . clean with wax & grease remover, tape it all off - then add your favorite Artesian Turquoise basecoat/clear to a can of reducer, shake & spray.  You can buy the clear (can form) right off the shelf at your local Car Quest.  Factory look - all done in your driveway.
