My Msport driver's seat developed an annoying squeak/creak a couple of years ago. I took the plastic cover off the side of the backrest and sprayed GT85 PTFE spray into it and that fixed it - no sound since. I've used this stuff to fix several trim squeaks in my car, I've also sprayed it onto the roll-over hoops so that it stops the roof catching on them as it folds down. It doesn't seem to mark any trim, so no risk of harm if you try this and it only costs about £2 a can, so not much lost even if it fails to silence the seat.


and WOW no more squeaking, groaning or creaking seat
