No..... Brave it fella !! You'll do fine
Just make sure to go through the grades of paper with not too big a step !! My grade steps were fairly big, and like a few mentioned you can always finish of with up to 2000 grit which practically brings the bike to a near polish finish anyhow !!
Go for it bud .... You want bullsy, im gonna strip my mint Coral Reef Klein Attitude if I cant find another doner bike !!! Ive always wanted to give a Klein a true custom airbrush paint job of my own
Did this to my Dads Motorbike last year for a bit of fun and its given me the confidence to do the push bike next
p.s Thanks for the nice feedback
always great to hear !!!
