what's a bloom?
Bloom is when paint takes a milky look. Can happen if you spray when it's
too cold. What the OP's actually referring to is fading.

Not always, in hard water areas it can be a build up of calcium. I saw a
Vauxhaul Velox in a dealers that was grey, when they cut back the bloom
it turned out to be two tone white and pink, all becasue the owner
washed it off everyday with a hose!
