What wrong with the claying? It's an awesome experience.
Sometime ago now I owned a Audi TT, I attended a Car show in Yorkshire & watched a demo on how to clay.......
I was hooked........I bought some not cheap I may add..........The following day I carried out the procedure....... I scratched the full back passenger quarter I was destroyed I could not believe I did this? or the clay exposed what may or may not of been there already??????
I had not had the car long a couple of weeks tops... had the dealer covered this up & the clay unearthed the scratches I dont know anyway I have never used it since.
I dont think I would of caused that much damage if I used wire wool.....And no I did not drop the clay...I just put it down to experience and never went near it again.
