Default Tpi Cracks ?

Why are both of my tpi plastic fender pieces cracked. In the same spot ? Is this common ? Should it be like this ?

Im redoing the car and not sure if im going to replace them since you cent see it much any ways.

My left one is off at the moment and it looks similar to yours, not sure if this is normal.

Mine is not like that, but it could have been caused by the rubber weather stripping that sits on top of it.

Must be common because I've seen it on a few different cars.

Dan...

You're looking at a 20 year old plastic automotive body component...


They crack...


It looks like the panel has been taken on and off several times... the previous installer may have something to do with it.

Also, the stress of the floating mass (the plastic being held by the tabs) being jiggled from the bumps in the road and pushed by air pressure in and out as well, puts a lot of energy into that small area... the results are next to your hand.




As a rodder... my cars have more vibration tossed at them than other cars of the same make, with a different owner... with lots of broken tabs on plastic and metal parts in my experience, there are some solutions...

My best solution for this problem involves a small bit of metal bent to the exact shape and a hole for the screw, some epoxy, and some fabric tape... this goes on the underside of the tab and onto the inside of the panel... be careful you don't want to add too much more weight to the panel... remember, the reason for the cracking in the first place.

Unless you want to buy a new part.
