It is indeed trickier than it seems and there IS a learning curve. You can see a distinct difference in skill from one half of the frame I painted vs. the other half .. I used a fan to blow the spray paint away from the inside of the apartment and towards the bike so it kinda created a mess when sprayed at 30cm.. I discovered that using the fan and spraying at a much larger distance creates an even cloud of paint that settles evenly on the surfaces...
As for your comments regarding primer, the primer used at car paint shops is the one used with an air compressor and a spray gun; something I won't be able to do at home. I am passed this point anyway
I am now trying to figure out how to correct the blotches and runs in the first 2 coats of white paint I just did. @Ronnno6 suggested I wait a week or so till the pain cures before I wet sand the imperfections...
any tricks or suggestions are highly appreciated
