I'm the proud owner of a 62 Dodge Polara 500 2drhdtp. I've only had it for 6 mo. for I was into MUDDY offroading with my Son in our 87 Wranglers. We PORed the underside of Both Jeep's w/the POR. It stood up to some pretty nasty punishment from the "ELEMENTS" GOOD STUFF if Subject materials are prepped right. We used the "acid first" also. Good luck! --------------------------------- Be a better friend, newshound, and know-it-all with Yahoo! Mobile. Try it now. -- [Non-text portions of this message have been removed]
