Explain how to make this bumper?

[fourgsixthree33]

I came across this on DSMtalk. They modified this stock 1gb talon bumper. The only description he gave on how he made it was...

as I mentioned in the "post your 1G pics" thread already, it was cut (red) and turned down in the front some degrees (green). and afterwards fiberglass + filler to look great again.

If someone could explain this, that would be awesome. I plan to try and do the same thing. I love the look. In the pic below, he made lines on the front bumper reffered to in his post. Green, and red. View the last pic for details.

Did he cut the whole bottom part off and just fill it or cut it and tilt it and fill it? I am confused on what he meant.

It would appear that he cut the bumper in half along the red lines, dropped and tilted it, and then filled in the rest with bondo or something.

I looks self explanatory..Looks to be two or more bumpers cut and meshed together to make it look aftermarket..

Yea that's what I'm getting from the photos as well.

I don't know... but I LIKE ALOT ALOT!!!!!
This is Something I WOULD LOVE to do!

 

[Palmetto_TSi]

this is awesome!!!!! my bumper was already cut right there when I bought the car! Looks like I just saved 15% by switching to Geico

 

[danielbo91]

Thats a sick bumper give us more info how the bumper is going to come but it looks like they cut it molded

See I was under the impression that he used at least 2 bumpers to make this one. But he said he just cut it and tilted it. Then filled it in with fiberglass. That's all he said. It looks like he just stretched the damn thing .

 

[Bud92gsx]

He could have used just two bumpers and fiberglass..You can make anything with fiberglass..

Cut , Tilt and drop it a little, and Fiberglass it back together. That exactly how i would do it. I dont see how it would take 2 bumpers. The fiberglass will fill in the empty space. If I still worked in fiberglass I would love to make a mold of it to re-produce them ### they do indeed look sick.

It does look clean.

Exactly what I was thinking about doing. If I could pull it off anyway. Not much fiberglass expericance. But I am sure once I get good at it, there are tons of things I could make and produce.

Fiberglass is easy. Basically sand the area you will be applying the fiberglass and resin. Coat the sanded area and the fiberglass pieces (on both sides) with resin and apply where necessary. Pretty easy, but easier to show than tell.

I would recommend not using fiberglass if you plan on doing this. Get an old junk bumper as well as some plastic bumper repair adhesive and filler and building it properly.

I like that look a lot. Fiberglass may be easy for some, but I've also seen people screw it up pretty bad on their first tries.

 

[fourgsixthree33]

I think it would take me a little bit to figure out. Maybe doing something easier would be a good idea. Jyumping right into a project like this probably would not end well.

I used to build boats and such.

Whether someone finds fiberglassing easy or not, it's the completely wrong way to modify a plastic bumper.

If anyone is actually interested in doing this themselves, let me know and I'd be more than happy to do a quick write up on the proper way to modify a bumper like that.

I'd be interested in stretching my bumper to allow for more air to hit my intercooler (when I get one that is), with out it looking like a hack job.

I would say he cut the bottom off and extended thesides and center pieces. Het a used one and start cutting and molding until you are happy with it.

Alright, here goes!

To properly section and extend a plastic bumper, you need the following:

-Spare bumper (can be busted, you're just using it for scrap plastic) or the same type of plastic
-Plastic repair adhesive
-Plastic repair mesh (usually comes in a roll)
-Plastic adhesion promoter
-Plastic bumper putty
-Aluminum tape
-80 grit sand paper
-Die grinder with an 80 grit disk

Your first step is going to be to clean everything with hot soapy water, dry it off, and then with wax and grease remover. I cannot stress how important cleaning before you do any work is. After that, cut the bumper you're modifying. I've drawn some cut lines on the bumper above to kinda show how much material you'll be adding. Obviously this is just an approximate guess:

Once you've made your cuts, you'll want to prep the bumper and filler pieces as follows:

You must be logged in to view this image or video.

1. Grind the edges to a V on the bumper and filler pieces as shown. Use your 80 grit sand paper to scuff back to where I've drawn the orange lines. This should be about an inch and a half to two inches back

2. This isn't shown, but use aluminum tape to hold the additions to the original bumper the way you'd like it to sit. Once you have it held strongly in place, spray on some adhesion promoter (let dry according to can), then apply a small amount of repair adhesive (grey) to the backside, spread it out to the orange lines then place down a piece of repair mat (black line). Push that down and into the repair adhesive, then apply some more adhesive. I'd recommend two layers of repair mat, but put them on one at a time.

3. Once the backside has hardened, grind out the front side a bit more, just until you start to see the repair adhesive in between the joint. Do just like on the backside, though you'll want to keep your mat below the level of the bumper surface. This way, when you sand it smooth later, you'll still have that structure.

4. Sand the front side to shape, then apply the bumper putty to smooth it out. Make sure you only apply over the bare plastic and not on any paint. Also, you'll want to put it anywhere you've hit it with 80 grit. Once hardened, sand according to product (different putties need to be sanded with different grits).

From there on it's basically sanding it to the proper grit for your primer.

Great right up! I think I definitely understand how to do this more than I did. I will try and get started once I get a spare bumper.

I didn't say it was the proper way. I don't have any experience doing body work so I didn't comment on that. I was just responding to a post that said fiberglass is easy to work with when from doing car audio systems, I know that it is not that easy without some practice. Thanks for making your most recent post though. It is very interesting to see how to properly do it. If I had a 1g I would consider trying this.

Great write up!!

I assume this is the same way you would repair a bumper? Is the plastic repair stuff flexible like the original bumper?

Please supply some names of good plastic repair products and where to get them.

Sorry, that post wasn't really meant to go against what you had said, I just wanted to make sure people knew not to fiberglass it. Fiberglass on plastic bumpers will crack apart extremely easily.

@gorf: Yep, this is exactly how you'd fix a tear in a bumper.
