It will not crumple... But goes to show that SS is not SS and also where water / moisture splashes are coming from * :o *:o
Or that some one is using a wet / contaminated cloth to wipe it down.
Bunnings has at least two SS polishes that I use.
A: Is a polish and nothing more -Qceder - Metal cleaner/polish
B: Has a mild cutting compound and great for removing slight blemishes - AutoSol - SHINE
PS. *Depending on; If the frame is Welded OR Folded, then that can also define what grade of SS might be best used.
PPS. Not all stainless is corrosion resistant *;D and thus it can be a trade off at times...
Just like high grade Ally used in boats... Also highly flammable and burns with ease.. The British Navy had first hand proof a few years ago.... A single small missile; (FOF was a joke then) can literally burn a warship / aircraft carrier to nothing (broad generalisation).
