Which would u guys is better? Which do u use on your fiero? Why?

those two products are for two totally different uses. bondo is for body repair etc. jb weld is for attching things etc if i rem.

I agree with Hockaday. Body filler (aka bondo putty) and JB Weld are two completely different things, and are meant for different uses. You shouldn't be using JB Weld as body filler, and vice versa.

One is for chemical welding plastics. One is for filling plastics and metals. You would use both to fix a cracked panel if you weren't using fiberglass.

I prefer using this ....

Actually, JB Weld bonds to metal extremely well, and would make a good body filler on a metal car. I don't know about plastic cars, however. To make my modified air cleaner housing in the picture below, I had to cut out the bottom of the housing, rotate it, and re-attach it, I also had to remove the snout, cut a different mount angle on it, invert it, and re-attach it. All the re-attaching was done with JB Weld, and it has held up through high temps and engine vibration since December very well.

I just completed a hood venting project, and used J-B weld for all of the adhesive requirements. The stuff worked excellent. I used late model Camaro dummy hood scoops, gutted them out, then installed then in backwards in my 87GT. Since I was actually doing more adhearing than filling, the J-B weld was the most practical way to go for me. Trick was to cut the hood holes very close to the shape of the scoops you'll be installing. J-B weld them in...sand them down, install your new and cool vented hood, and you're ready to go !
I've posted this before, because i was very surprised on how convient and easy the project was. It came out great,thank God.
So J-B weld is the way to go, in my opinion, of corse.

I fixed a radiator with JB Weld once, and I built new quarter panels from Bondo, but that was a long time ago and I don't want to talk about it anymore...

Fixed a broken piece of concrete on my drive way with JB Weld. It is still holding.

Once I had a ’87 X1/9. Was driving it, about a week after buying it, when suddenly, it jumped out of 5th gear and wouldn’t go back in. Got home from the drive, looked at the transaxle and found a very large hole where the CV joint had evidently come loose sometime in the past and hit the case. Trans fluid had been leaking out for some time but only when I was driving.

I pulled the end off the transaxle (5th gear is at the very end) and found that not only was there no grease but the shifter fork had almost worn off one side, precluding going into 5th.

I bought some JB Weld, cleaned off the trans case, sloshed a gob over the hole, let it set over nite, replaced the shifter fork, put in trans oil and drove it 2 more years, no problem..

That has to be a first—rebuild the trans case with JB Weld. When I told my friends, they said, “I’ll never hold.” But it didn’t even seep.

Had a co worker with a Omni that had a stripped head where the plug went in. He JB welded it and it last the rest of the winter 3 months before it came out. Amazing stuff.

As for Bondo, do not use it on a Fiero for body filler etc. You need to get Everflex or other products made for flexable bumpers. Bondo will split and crack and not work well at all.

Where is the best( cheapest) place to buy that evercoat fiberflex stuff? I need to repair the hood of my fiero around the sunroof with this stuff before I can paint it.... thanks guys....peace

You only need to use flexible fillers on the front and rear bumpers. You dont on the rest of the body panels.

BTW, JB Weld DOES also make a flexible product too.

J B Weld will work, but it sure doesn't sand easily.

For adhesion - J B Weld.

For body filler on roof, deck and hood - Evercoat

Does anyone know the best place to buy that evercoat fiber stuff? I need some for my cars roof and I want to get the best deal on it? Thanks and peace
