Default Cutting rear fenders.

I am in the process of instilling rustys offroad fenders on my jeep and have reached a issue. The rear needs some trimming. I had different fenders on here before and cut to the pinch seam but now it needs more.








I would like to cut it even with the rear quarter guard but that is a good bit beyond the pinch seam. Or would it be best to trim as much as I can and leave it.

I have those same steel fenders from Rustys. I cut as much as I could, then made some vertical cuts and hammered it flat with a dead blow hammer.

Ok thanks for replying but after looking at them for a hour I made up my mind and cut the crap out of them. After I cut it I realized that it was not going to be to hard to fix.

As long as you can weld well, you should be good to go.

A number of seams in the Cherokee are glued. I don't quit know what you are doing with the exposed seam but after you get the seam closed up you could fill the back side (inside) with some kind of glue.

Automotive seam sealer. Only right stuff for body panels.

I started welding them up and I think it looks pretty good. The wheel well is much bigger than stock. That kind of steam sealer have you tried. I use some from my local auto body shop and didn't like it and it was 20 couple dollars a tube.

I didn't use seam sealer. My fenders were only trimmed to the mini flare and then bolted together. I back filled the seam with expanding insulation foam. I probably should have used seam sealer. The welding job looks good.

That foam crap collects and traps moisture..... Your fenders are going to rot out

I used the seam sealer that advance carried. Goes on and takes a couple days to get hard but works great

I don't think the expanding insulation foam collects (absorbs) moisture, but I agree that it could trap moisture. I only sprayed it along the top and partially down the front and back seams. Not in the cut and folded fenders. Anyway, I do believe that the auto seam sealer a better bet if your going to put anything in there.

X2 on that, I used the foam crap before to and it definitely does hold moisture, rotted the crap out of the metal all around it.

is it just me or does something look funky with those leaf springs? Seem awfully flat in the middle. Reminds me of when I broke a leaf in an old YJ that I had.

Might have something to do with how many leafs he has in the pack.
