I have used the Colorbond product on some test pieces and it appears to work very well on all except the door sill trim, sails, the very bottom piece of the 94-95 door panel and kick panels. Those parts are made from polypropylene and does not paint well. I am now looking for the canadian version 89-93 black sail and door sill pieces. The black kick panels I should be able to find at a local bone yard and for the bottom of the door panel; I do not have a plan yet.
