End of last summer I coated any place I saw rust any where on the car including undercarriage, rear wheelwells/lips, hatch inne lip, inside rear doors on the b pillar seams. So far the only reoccurrence has been slight spots on the undercarriage and the inside edge of the rear wheel lips. I am going to sand the rear wheelwell lips to bare metal, which I didn't do last summer and re-coat with Por15, then topcoat with metallic black.If you apply the POR15 over the paint without taking the area to bare metal, it will peel,as it doesn't adhere well to paint, that was my 1st time using it, so now I know it must be taken to bare metal. Any areas where I didn't use high pressure water,from the hand wash in winter,remained as they were after last summer's application. We had an extrememly harsh and heavy snowfall winter season here in Mich.last winter with excessive amounts of salt, so I had to spray the car often at the hand wash. I do have some dime sized or smaller spots on the roof from gravel hits(**** the scumbag Mich. gravelhaulers(fu) that have also broken my windshields and fog lights)that I never treated, but will be sanding down only within the spots and apply the POR15 smoothly as possible, topcoat with black metallic and rub the entire roof out with different polish stages and my rotary polisher. To see true effectiveness of POR15's ability will be when it's looked at carefully after a long hard winter.To the guy who spent $240 on the repair, good luck, before I knew about POR 15, I had that done too and it came back, but I spent more than you did and I wont do it again, I will do it myself and save the money. I actually enjoy taking the time to correct these problems on my own. I do not (knock on wood) have rust around my emblems, but if it's not too deep you might still be able to stop it with some time and effort.
