Hi
I'm going to spray cellulose top coat and wondering if its normal/ok to lay down all layers in one session - ie. one after another with flash off time in between instead of spraying a few coats - leaving it for a few days/ week to harden and then doing another round of layers. I've read that some people spray up to 7-8 layers to get colour depth and thickness for cutting back. With this number of layers in one session is there not a danger of cracking once the paint shrinks and hardens?
I've sprayed about 3 layers before in one session with aerosol cans, not a spray gun, and it cracked with primer showing through. Maybe spraying with a spray gun gives a more robust finish over aerosol cans as there's better atomisation and no propellants involved so maybe cracking is not so much of an issue (just a guess). Can anyone advise please. I would rather lay all the layers down in one session rather than fuss with separate sessions. Summer is ending so I want to finish painting as soon as poss before it gets too damp and cold.
thanks.
