I am wanting to spray my bike frame and I am thinking of using a few tins from a local auto/paint shop. I have come across tins of primer, gloss paint and clear laquer in acrylic at a decent price. Is it any good and as safe and easy to use as cellulose paint I have only a rear triangle and three foot of 2" tube to spray and dont possess any air equiptment....well only a track pump. I dont want to use hammerite paint either.
