The problem with the aerosol paint is that it scratches very easily. I had a new deck cover bent to replace the original one when I added a blower and had to shorten the lid, then used a spray can from Grasshopper to paint the lid, it looked good for a year or two then it started to look scratched up as the paint never seemed to get as hard as factory paint. I agree it all depends what your expecting to get from the paint? if its long term, mixing and air spraying commercial paint is the only thing that will hold up plus they have computer programs that look at your color and can then mix a very close duplicate color.
