Doing my nosey neighbour routine the other day I saw this chap polishing his pride and joy (worth about 300 notes but in good nick) with WD40 of all things. Seemed to give a reasonable finish although I was about 40' away so it may be crap close up.
I used to use pledge on my motorbike, but WD40 seems an odd choice as a polish.
Is this method strictly for numbties or does he know something we don't?
We used to use it on racing engine and gearbox castings. Just spray it on and leave it overnight. Next day it appeared to have soaked into the casting and it all looked like new.
Yes it leaves a lovely shiny looking finish, but its oily.
If you coat your external paintwork in this, everything just sticks.
Ok for protecting some engines and stuff.
