Hey guys.


Well, today was a beautiful day here, so I figured why not do my ground effects/bumper cover.

My friends are a bunch of smartasses, so rather than hear "but your car isn't a Supercoupe...you're a poser..." what I did was this......

To get rid of the "SC", I scuffed up the indented area with some 80 grit paper. Then I filled it off with bondo, just so that it was about 1/8 of an inch higher than the surrounding area. Then I sanded it smooth with a palm sander, and 80 grit paper. Once it felt smooth, I finish sanded it with a piece of 400 grit paper to get rid of the cuts from the course paper.

This is what it looked like:



Blew off all the dust, and then primed it with just an automotive spray bomb grey.

I gave it about six thin coats to make sure that it coated the filler nicely.



Then...my favorite part......fired up the spray gun. Five coats of Nason later, and this is the end result.



Can't wait to get it on the car tomorrow!

You don't care that the Thunderbird script is completely off center? That would drive me insane.

Not really, Im thinking about incorporating a "4.6" where the SC was somehow down the road.

Are you sure the bondo is going to hold? I would think bondo would just flake out as soon as the bumper flexes a little. Its too bad you painted it already. Hopefully it will hold up, but if it doesn't, you can get flexible sandable epoxy that is used to repair rubber bumpers and fill it in with that. That's what I used to get rid of the "mercury" in the left corner of my front bumper cover, and it hasn't cracked or anything.

Man that looks like you did a good job.

Good luck on the bondo....that stuff is only good for very shallow fills.

I ended up using a "rigid" plastic filler on mine. just my $.02

People have no faith in bondo, its really not that bad....if used properly on what it is designed for.

If you pile it on thick, especially in a pressure or stressful area, then ya it will crack. The "SC" wasn't all that deep, and I can't see the bumper being all that stressful.

Also, it sucks in water because of the cheap resins used in it, but I don't think that will be a problem given the location.

I use all kinds of fillers daily, boats and canoes are my job, what I have find are the epoxy based fillers, while they are superior, are overpriced and require different finishing procedures than good old car in a can, especially for something like this.

Now, if it was a boat, or even a canoe.....bondo wouldn't even be an option. For light filling though, on something I own.....it should be ok (knocks on wooden computer desk)

If it cracks in a week, I will be a man and come back here and post it.....lol!

Again, it depends on the repair.

My 1992 Taurus SHO is living proof that bondo is fine as long as it is not used in a stressful area.

Five summers ago, a sailboat ran into the front corner of it at my shop. It punched a dirty hole right on the corner of the bumper cover.

I took the cover off, repaired it from the underside using only polyester resin and chopped strand matt, and feathered the edges on the front side using nothing but bondo. Primed/paint, five years later I still see the car and it looks fine.

Also...in that picture that was linked up, you can clearly see how long the crack is, meaning someone has caked on bondo like crazy.....applied it on the surrounding area to the SC. If you put it on like that, of course it will crack, not a question of if, a question of when.

Once again though, if it does crack, I will come back here and eat my words.


*edit* also in that pic linked up, buddy said he was backed into by another car. I don't expect any kind of filler to withstand that kind of impact.

If the surface is prepped right then the filler will be alright. I used a bondo filler and when It was hard and sanded I flexed the bumper as much as I could to try and crack it out of the letters but it was in there good. The letters are not very deep at all so it's not like a big glob.

Nice work, I couldnt of did that...yea you for sure need something to fill that off centerness, doing a 4.6 somehow would rock.

There was someone around here a few years ago that had incorporated the "GT" lettering from a Mustang bumper cover into an SC bumper cover...looked really sharp.

The bumper repair epoxy will withstand getting backed into, or rear ended, or pretty much anything that the original bumper would have withstood. If the bondo works for you, that's great, and I hope you don't end up having to repaint the bumper again, but just for the future, you might want to consider that other stuff. That's all I'm saying.
