is this rustproofing or part of the rocker? i was taking pics of the underside of my car tongiht and found a section of that rough stuff on the rocker looks like its all bunched up. i thought maybe sometime this year something caused that to move but i tried moving it with my hands and it won't budge, and i also found a pic of last year showing what i think is the same spot bunched up like that
is this anything to be concerned about? the car has 127k miles, is 15 years old, and hasn't seen a single northern winter btw.
this was taken last year and i think i can see the same bunch up of stuff in the background so i don't think this happened over the summer. i wonder why that would have moved or could it have just been an error in application? the white stuff in the foreground is probably paint or something, its the bunched up stuff in the background i'm referring to

i never have either. it's a southern car and i don't drive it in the winter up here. as for kissing a curb i'm not sure how that would have happened. its right in the middle of the drivers side of the car and there is no bend in the metal just the undercoating is shifted over. my guess is that maybe it was lifted up somewhere near there at some point maybe. i was just wondering if thats a factory coating or if it was added. it looks like its been that way for a while. I'm guessing maybe before i bought the car 5 years ago and i just never noticed it. the other pic taken last year i didn't notice it in since it wasnt that close to it.
there is a bend on the other side which i'm 99% sure is due to a blowout in the everglades back in 04 and the fact a florida helper had to use a floor jack to get under there to change my tire (i didn't have a jack so i had to call them)

it almost looks like maybe it was on jackstands or something when it was applied and they sprayed around that area instead of on it. hence the buildup around the spot thats bare. my carfax says that w/ 75k
Vehicle serviced
Paint sealant/undercoating installed
ABS system checked
Cooling system checked
Rear brakes replaced
Drive belts checked
this was done in 2002 at a dealer in pembroke pines, FL by the original owner.
so maybe the dealership did install an underbody rustproofing at that point. hmm.

The stuff on the rocker panel itself is there from the factory & while they look the same, it's a different material that what the dealers use as an uncoating. Anything beyond the rockers and rear wheel wells was added after the vehicle was built, by someone other than GM.
Mine also has those same "flattened" spots on the rockers & has since it was brand new.

i do wonder why it appears the underbody of my car is unpainted. i've seen red and white and other color fbodies with shiny underbody paint. maybe thats the rustproofing. maybe my floorpans were repainted with some sort of rustproofing paint since they appear dull? or is that just how black cars are underneath?

You are probably right that it happened when someone didn't lift it properly.
It is GM undercoating intended to stop stones etc. from chipping the rocker panel paint, provide rust protection, and to keep noise down. You could carefully cut the excess off, straighten the other area using a hammer and dolly and then recoat with good quality undercoat. I use either Eastwood or Duplicolor rubberized undercoat.

thats the weird part. there is no bend in that area. thats why i don't think it was necessarily caused by a lift. there IS a bend on the passenger side as shown in one of the pics and i'm pretty sure i know where that one happened, btu the one on the drivers side isn't near a jack point and there isnt a bend in the rocker itself or the frame rail (where the bend is in on the other side)
I could probably just spray that area as is but is it necessary? i wonder how long it's been like that. since the car doesn't see snow/salt i wouldn't think that area would be any more or less prone to rust than any other area?
