Replace Cross Hairs

Silver-Shadow · Post by **Silver-Shadow** » Sat Mar 03, 2012 9:55 pm

Many srt4 bumpers have the cross hairs removed. Usually to show off the intercooler or just because. Can the cross hairs be put back on the bumper?

They are cut from the bumper.. and the bumper being neoprene even if you managed to plasti weld it back on not sure how long it would last. better off finding a complete one

Don't you mean polyurethane? I'm 99.99% sure they are poly. As far as replacing the crosshairs..IF you have them still..its possible. You'll need a good body guy to get it all to line up and look correct, but it's possible. The way they repair the bumpers makes that area a little Pita to work on.

Yea neopreen, poly It's all the same flexible stuff lol... But I would think the amount of money to get it perfect your better off getting a another one. There is not enough material to bond the pieces back together and hold strong. One bump and all that pretty work will be destroyed

Neoprene is what they make seat covers out of, Polyurethane is a plastic..lol

There is enough material to bond it, and it bonds strong one plastic welded..it'd cost you around 400$ for a shop to do it tho. Then they'd need to prep/paint it, yadda yadda. Luckily my dad owns a plastic welder, so when i go to mod my srt bumper to fit 02 headlights, it'll be free..lol

They are both kinda right ...

Heres a good article about the different types of
"plastic" / "rubber" bumpers and other parts used on cars.

If you are going to try to repair / replace them ... I would recommend using this ...

Now ... to answer your question ... yes with enough work it can be replaced ... BUT ... wait let me fix that ... BUT ... thats a really big but there ... as Caraudioholic24 pointed out ... it wont last. You are wanting to repair something that is part of a molded piece that has been completely removed. Any sort of jarring to the bumper will cause cracks to show or for it to even pop right out, depending on how hard of a bump it is to the panel.

I wouldn't waste the time / effort / money to try this. You would be better off finding a bumper that still has them in it ... even if it has scratches or nicks out of it ... the you can use the repair product listed above to fix those issues.

IF you can get Permatex plastic weld to bond to it, I doubt it would break loose.

But it is dependent on how well it adheres to polyurethane.

If my GB intake can handle a radiator being shoved into it, and still has not cracked 60,000 miles later, I'm sure Plastic Weld will hold up on a front fascia, if the bond is good.

I bet my intake sees more vibration than a fascia does.

But getting it to look pretty and hold up, well I'm not promising anything there. If you used metal on the backside for support with the plastic weld, possibly. It will bond about anything together.

Yup. The plastic welder i have has a setting for Poly, and comes with poly rods to fill in the weld. Take a dremel around the area where you want to "weld", cut a V groove, bevel the edges, place and "weld". Its alot like heavy metal welding to be honest.

Strength wise, IF you can get it to bond right with the weird angles that you'd be doing, it would be somewhat strong. I smacked into a dog in my M3 and it made 2 1' cracks in the bumper cover. I fixed them, and the area that was fixed was stronger than before...so its all application biased.

Imo, just buy a new bumper if you want them back. One COULD fab up a removable adapter for the crosshairs out of spare sheetmetal, but it'd be all..ghetto.

Take the crosshairs, rivet the sheetmetal to the inside of them(where its hollow-ish), cut a hole where they'll join to the rest of the bumper, bend the sheetmetal to go flush with the inside of the bumper, rivet away..etc. You get the picture. There are several ways to do it, but its all a massive PITA when you could just buy a new one..lol

This is the welder i own. Its not some glue based one, but an actual "welder"

Just fiberglass the crosshairs back on. Bondo the seams. Re paint.

The bumper is actually made of TPO Thermoplastic PolyOlefin. That is your fun fact of the day

Oh and on topic, you could....if the right products were used but you're better off finding one where they're still there in OEM form.
