Warm bonnet machine polishing? Over-cautious or genuine question?

[Darren S]

Chaps,
I'm helping out a m8 who's bonnet has football scuff on it from kids playing near his car. He's about a 25 minute drive from me, but could I just make a start on the car straight away, when he gets to mine?

Ironically, I removed three surface scratches from his passenger door about two weeks back - and now this happens! I'm mentioning it as the front area of the car (BMW 330ci) appeared really quite warm. I know its a cardinal sin to machine polish in direct sunlight. But can the heat of a switched off engine be just as detrimental? Or am I just being OTT?

Cheers,
D.

Just as detrimental I'd have thought, given the heat is going to affect the way the polish spreads, dries etc.

Hose it down first. Assume you'll be washing it anyway first. No issues then.

Yep, that ^

Cheers guys. I'll get the bonnet cooled down when washing it.

Thanks again.
