Pinch Weld Pounding!

broncsrule · **Posted:** Wed Sep 27, 2006 12:12 am

So I put my Moabs on and now I have severe pinch weld rub. Can't seem to find a "How to" on this now. (even though I recall seeing the write up somewhere before)
Can someone lead me to this thread or give me thr directions again--before saturday.

thanks in advance

Yes, that helps...thanks

If I don't have a heat gun. What is the other method? Remove plastic cover, pound, primer, paint?

I cut out the plastic around the pinch with a Dremel - cut off wheel and sanding wheel. Pound flat with a small sledge hammer, it's not that difficult. Then finish the hole over the pinch with spary on rubberized undercoating, check any autoparts store near the bondo. Apply several thick coats to completely fill the gaps. Having the wheels off makes it easier. Put newspaper underneath, this stuff is thick and drips down as you spray it.

The best part about this process is the looks all your neighbors will give you after spending a half an hour or so pounding on your Jeep with a sledge. It doesn't get much better.

It is easy, just get a good hammer-the heat gun makes it easier but is not necessarry!

Is the "rubberized undercoating" what others have used to protect the bare metal?

I should have took pictures. This is what I did for maximum clearence/minimise structural integrity.

Bought replacement plastic rivits from Napa - I did not have the rivit gun, worked ok but tighter if I had
Removed the grill, bumper, plastic fenders and fender liner (sounds hard but not that bad)
Put some relief cuts in (not on the spot welds including thought) including 2 v cuts at the turn points.
Wire brushed and sprayed some undercoating spray and while still tacky
Pounded inward (to engine side) for the fold and got a small maul and pounded more till nice and rounded
Picked out the paint flakes, added some foam filler for a gap and then more undercoating

Turned out nice. Drove like this for a couple months. Almost never put them back in but there are problems sealing to the plastic fenders.

Today I fianally cleaned it all up and put the fenderwells back on

Removed wheels, fenders and liners
cut out all of the bump plus some
scrubbed clean the area and dried
I used 4" super sticky roofing tape (has alum foil on one side)
Applied tape on ouside of plastic fender lining.
Reinstalled fender and fender lining
undercoated the affected area

Look Ma Alll gone!!!!

Tip of the day - The Roofing Tape worked great in combo with the undercoating

------------------------------------------------

I could see 2 variation

1 Cut liner in place, pull out as needed to mount roofing tape inside (hard but do-able)

2 Cutliner in place, put roofing tape on outside

Both - Undercoat

Hope that helps - KjHawaii

One thing that will make the pounding far easier is to pinch the metal with a vise grip type of plier, then bend it. Then you only have to finish the job with a sledge instead of trying to evenly start it.
