Small tear in my front spoiler. Thinking "better life through chemistry" (e.g. 3M has gotta make some sort of "silicone" product I could fabricate/mold the missing piece and glue into the seams of the spoiler). New spoiler = $4k+ ... and this damage doesn't warrant the expense. Anyone got suggestions?

Cheers,

Ouch, how did this even happen?

Thread and needle, stitch her back together and apply and silicone or rubber patch over to smooth

@Angryinch - Great minds think alike. Not sure straight silicone will have the tensile strength or adhesive properties to last... I'll look around my old man's machine shop and see what he's got... gonna use monofilament on the stitch work.

@Beherit - Track Day. I ran over some car parts from a crash that occurred ahead of me while in Sport+ mode (spoiler down)... fortunate this appears to be the only real damage.

On second thought, this is the seem where some of the spoiler comes down, IE the front comes down but not the sides, I believe at certain speeds?

Repair might be hard here unless its secure, its a flex/transition point.

Might be worth a shot to try stitch it and see what happens.

That sucks.

Definitely gonna have to stitch that up then a silicone adhesive. Something that will be flexible when dried.

This is what I would try:

i know you might think this is "out there on a ledge".....but i would show the pictures to a dentist - they have all kinds of materials that might serve this application exactly as needed (acrylic compounds come to mind) - "you never know" - Good Luck !

I would change it. I think a repair or not fixing it will effect aerodynamics.

I second this. Just come up with 4k + , replace this and do it right. Shortcuts on a car like this is ill advised plus if you sell you just pass the problem to buyer.
The car is seriously unstable with the aero compromised.

I would just get the spoiler replaced.

A repair can be done easily....if you choose, but you may be able to submit to insurance and just get a new assembly......that is what I would opt to do if my car.....BUT, if you want to DIY......

You could use rubber material from a bike inner tube as a thin backing behind the tear and then use E6000 as the adhesive to hold the backing and cut surfaces.....its waterproof, clear in color, flexible, great hold......can be bought on amazon or at a hobby store......or even grocery store......

I have used on my cars before and it has held for years after one application......I think the key is the inner tube backing for extra strength and it also serves to "hide" the tear and glueing into place to hold the cut flush.......it can be done....use a small vice or clip to hold it in place during drying of the adhesive......

Keep us posted on what you do as it may help others with same issue....

you could also try to plastic weld it. Go to Harbor Freight and buy a plastic welding kit.

If it were mine, I would repair it - like with windshields, the minute you replace them, you 100% will get a new rock chip the next day . . . I'd save the new lip for when I sell the car - if it's a driver, do the repair, and save the virgin new unit for later.

This should be a standard composite repair - use some cloth on the back with West system epoxy . . . or similar. . . then do some basic paint work on the front to hide the rear patch.

Wish you could have my old one the dealer replaced because of my spoiler faults and when I picked it up, it still had spoiler faults 🤦🏽‍♂️
