Must admit to finding rattle-cans useful for small jobs like brackets etc when it's not worth firing up the compressor and all the associated clean-up .... and for jobs that aren't huge (like motorcycles where it splits down into a few manageable parts) you can do a remarkably good job with them if you're prepared to put some time into the prep and flatting/polishing after.

Totally agree regarding graffiti .... just back from Portugal and the towns are as bad, if not worse, there. It's a modern scourge.

Now I have nothing against real Street Art and Mural painting .... the problem is the 'Taggers' .... constantly repeating their pointless logo in some odd game of 'I can deface more than you can so I win' .... fundamentally pathetic and weak people scared of their own mortality ... wanting to leave behind some tiny Cosmic squeek of 'I was here' ..... catch them and put them on clean-up crews removing their scribbles .... might be a learning opportunity on the subject of the futility of leaving a lasting mark in the face of the crushing length of eternity! 😁
