You know.................spray outfits both HVLP and conventional are dirt cheap these days, and offering from Husky (Home Depot etc.) work fantastic.
With all the work that goes into your bike, getting "real" paint is really easy, and it will last. No matter what you do, rattlecan stuff sucks.
Just my opinion, but rattlecan paints fade/chip/peel/etc. sooner than later. Been there, done that, and never again.
Granted, rattlecan is easier, but it is not really legit for bikes, patio furniture and a birdhouse (plans from Popular Mechanics June 1976) maybe, but the difference is night and day. All that work, and then to rattlecan at the end, a waste IMO.
It's like the Hillbilly that is proud as can be that he welds with a coathanger, but welding rod that is correct is dirt cheap and everywhere, it is the hallmark of a hack, not a craftsman.
Anyway, do what you want, but I have been painting since the mid 1980's and I PROMISE you will be sorry down the line.
Below is real engine paint (with catalyst)- I can spill gas on it, and not sweat a thing. It will be perfect 10 years from now. Costs $45.00.
