When you guys trim the rear fender, what do you do to keep the inner and outer fenderwell together? I've don't remember reading anyone having a problem with that.

I'd guess run a few short beads along the seam?

cut perpendicular to the desired line then smack them over with a 5lbs sledge....keeps the stock pinch seam in place....

I meant to do that this summer... and I forgot until you brought it up... Hasn't been a problem, yet

I was thinking of using some door edge moulding around the wells on the edge. I guess I could run a few small tack welds just to hold it together and try not to burn the paint too bad. The duplicolor paint I've tried doesn't work too well.

Bending it over works, but the sheetmetal distorts some and it's not a nice and pretty edge like it would be with cutting it. Plus I will need to paint all of that as the bare metal will rust in short order.

I'm not too concerned with it falling apart, but having mud, water, etc get up in there probably will cause it to rust out quicker.

I door edge'd all my cuts, then left them on when i bedlinered the whole jeep. So they are there forever, and makes a nice little seem.

duplicolor really sucks. I don't know why anyone likes that crap. I've had my best luck with ACE brand "premium enamel" of all things. Stuff sticks to any surface and goes a long way too...painted two vehicles with the stuff not to mention the zj's rockers, bumpers etc...

boo hoo, it's not as pretty but it's stronger. ;) in the front i did the door edge molding and that's all well and good when you have a single wall fender, but in the rear, I'd rather have the structural integrity.

I drilled holes above the line I marked to cut, and riveted the 2 pieces together every 6 or 8 inches. Then I made my cut, taped off about a half inch line along the edge of the fender well, and painted it flat black. Looks like crap, but I figure I'll probably try to cut more in the near future anyway.

Ace doesn't make paint that matches for me... Duplicolor does.

Hank, that's an idea I didn't think of.

I was looking at 95ZJs trim job and I just found it hard to believe that no one had talked about the fenders coming apart.

Trim to red line, that's what I'm talking about with this post.

The 90 degree fold is also tow layers. I took off the lip makeing the inner fender seperate from the outer. RI removed the inner trim panels and filled the gap with spray foam. Haven't had any issues of the two panels seperating. A gap is created between the inner and out fender panel when you trim that high.

Ok. I guess spray foam would work. I just don't want mud and shit getting up there and rusting my Jeep in a few years.

Foam works perfect...

To prevent the foam from soaking up water, I'll put underbody coating on it.

The underbody coating protects the foam from water and mud.... I tested it:

Before I put the edgeguard on it, I painted the cut:

There you can see the door-edge-guard... that is a 33" tire:

Thanks for the help deadman and everyone else. That's what I'll be doing.

Now to figure out how much trimming for a 35.5x11.5.... hmmm. I'm gonna go mount one up later on and take some pics. A 35" Claw fit ok, but it's really only a 34". Stupid undersized tires.

I've got to quit looking at stuff like this...


Now, it's got to warm up so I can go outside and do some body work.

Nate, how much lift are you running? I have a set of 35's sitting in my garage and have been contemplating making them work. If not, I was thinking of trading them for a set of 33's (buddy won them in a raffle). I have LA's with 4" RK springs and a BB.

I trimmed mine like the picture back there and I have 35's with 5.5 " lift...
I do have adjustable arms though...

nate

I have around 6" of lift. Going to probably run a Q78 (35.5).. run some RK 7" coils....

You all are thinking "ah, it's too talll... you will tip over and DIE" Right now I have 6" and 33s... the 33s still rub.

Yeah, I'm thinking if it's a matter of ground clearance, I'll put my axles on the lathe to gain the extra inch from bigger tires. With a 5.2 and the propensity to use the skinny pedal, I really don't want to have to move up from the hp d30 right now to be able to happily wheel with 35's and not worry about breaking.

I think I'm going to trim this week and borrow a set of 33's to see how it looks.

I was talking to an auto body guy I know and he about freaked when I mentioned spray foam :smt003 I guess it holds moisture to the metal and causes it to rust real quick.

What I'm thinking is filling the gap with fiberglass... or I suppose I could duct tape it then bondo it too :mrgreen:

It has been a year now since I used the spray foam... no moisture or rust whatsoever. The foam is dry... I've removed the plastic and the carpet inside my ZJ. So after I read your posting, I went outside and looked and felt the foam from the inside. It is dry. Did I mention it rains like over a 100 days in the year over here.


Your bodyshop guy just thinks it will host moisture, and sells it for the truth.

I guess fiberglass/bondo will get cracks and possibly brake by the movement of the unibody. Not sure tho... it could work just fine, dunno.

The auto body guy isn't lying. I have a 71 FJ40 and the back had alot of spray foam to cover up small holes. Well I pulled all the foam out, and the metal under the foam has rusted so bad it pulled off with the foam. Pretty much wherever there was foam is now just a huge hole. Now the Jeep sheetmetal is galvanized, which I'm sure helps... dunno, I'll figure something out.

I'm trimming out all the extra metal in the front know... all that stuff by the battery tray, etc is gone. :supz:

Ummm, yeah. Sparay foam will hold moisture, there's no question about it. Even bondo, if not primed/sealed over properly will hold quite a bit of moisture, and eventually lead to cracking and rust. We all know moisture + metal = rust.

Don't mean to hi jack this but I have some rubbing in the front, anyone got any pix of what they have done up there?

I currently have only a BB but am running 32's and when I tun into a parking lot or something that is sloping up the front drivers side rubs (I am not sure where exactly I still need to flex it out at the house to see what is hitting).

I have already taken the lip of the front fender and beaten it flat against the outer part of the fender and have bent the entire fender out as much as I can by hand but still gets a little rub now and then.

Does anyone have some close up pix of the door trim you have put over the cut edge? i am not really sure I want to trim much more and if I do I want to be able to cover the rough edge in a way that looks as close to factory as I can.

My bet is that you're rubbing on the outer fender lip.

I hope this is what you're looking for. Not the best pic in the world... I just zoomed in on a poser flex shot I found. I had been wheeling it for a couple of months by the time this pic was taken, but you can get an idea of how the stuff is used and where it goes. Its just some door edge moulding that I got from AutoZone. I got the biggest size they had (in black - my jeep is anti-chrome) sitting on the shelf. I'd suggest putting a dab of glue every few inches just to keep it in place.

Hope this helps:

I've still got a pack or two sitting around somewhere in the shop. I'll try to take a pic of the packaging if I get a chance this weekend.

Yeah I got some of that at Napa. It was around $20 for a 50ft roll. Self sticking too.

I started to look more closely, and it seems that as long as I don't go too high, like maybe 5/8" or so, the 2 fenders should stay pretty close together, enough that I can clamp them together and tack weld them.

Am I wrong on this?

Swamp boy
04-10-2005, 12:53 PM
Seems plausible but I dont know if the tacks will hold with all the motion of the Jeep...

IT may work .. Cant hurt to try...

nate
04-10-2005, 05:19 PM
Yeah I don't think the fenders move around too much against the out skin. Could be wrong though. I cut the pinch weld off the front and welded that up... so I hope I'm right. Shit will probably fall apart on the first trail.... oh well :supz:

Heres my front and rear for refrence. I'm running 33's with 2 1/2" up front and 1 1/2" in the rear using stock control arms. I only needed to trim the inner fender well up front. In the rear I welded the seam, but never smoothed it out.
