    black paint around bottom of car

    i want to respray the lower areas of the car, because of chipping,ect. should i sand, prime, then spray? or should i just sand and spray? would rattle can VHT black epoxy paint work well? or should i use a real spray gun? also if i want to shadow line at the same time, how do i get the trim off, and do i use a flat or a gloss spray? ive also heard of barbacue grill black spray paint, what do you all use that for?

    for the shadowline: SEM Trim paint. I think the # is 1493.

    for the rocker panels, personally, I'd take some 3M wax/goo/whatever remover, go all the way around, tape teh area off, and go over it with something toughter...a truck-liner type stuff.

      go for the SEM Trim black for your shadowline. any other type of black (flat or glossy) will not match the original finish and will look retarded.

      for the rockers, I don't think sanding is neccesary. You'll want to clean it really well first though, maybe scuff it up with some 3m pads.

        For the rockerpanels, I bought some 3M Rubberized Undercoating spray in a rattlecan. I used Goof-Off to get all of the tar and road grime off of the rocker panels. Then just mask it off really well and start spraying. It took an entire can when I did mine. You'll have to wait a long time for it to fully dry though so I wouldn't plan on doing it before you have to go somewhere... I'd recomend a full day to do it.

            I re-sprayed my rockers a few weeks ago as well. Turned out great with some advice from TJ. You don't need to completly remove the old undercoating...just make sure its clean, then spray. And I only masked off up to the door moldings, because there is not much overspray. After a few coats, I let it sit for about three hours, then removed the masking tape and let the car sit until it was dry. But if you do re-spray your rockers, make sure you don't need to use your car for that day, because the rubberized undercoating takes a while to dry.

            BTW make sure you leave about 10-15 inches between the can and the rockers, so it comes out evenly or else it wont look good.

              Excellent. Take Kenyon's advice. It takes a LONG time to dry.

                mar-hyde Rubberized Under Coating

                it is what TJ used and I found it for myself at the local Advance Auto Parts. I'll see how it works sometime
