If you're lucky and know someone that is set up for sand blasting, you
can lightly rough it up that way. It's a pretty small job and someone
may do it for a really low cost. You need to be careful if you rough it
up with emery cloth or some other way cause it may take a thicker
primer/paint coat to smooth it if you scratch it up while scarfing up
the chrome to get a good bite. It's also harder to hit every single
spot doing it by hand. I've had that happen doing custom paint jobs on
motorcycle tanks when I get a little lazy with the prep work.
Apparently when you are are working with a chrome surface, a two part
zinc phosphate primer works really well under another coat of urethane
primer. Urethane primers and paints are really toxic so you NEED to
have at least a really good respirator when you work with them. They
are also pretty expensive.
If you do go ahead an try painting your frame, keep in mind that good
preparation is the only way to get a good paint job. If you want to
save yourself some trouble working around the lower end, maybe mask off
a few inches above the frame brackets making it a two color frame:
Chrome on the lower end and paint on the upper end.
One thing that's pretty common is to get runs or "orange peeling" on a
paint job even if you use a spray gun.. More common with rattle can
paints.. Use grit beyond 1000 that ya can get at an auto parts store
and wet sand it (with plenty of water) up to 2000 . If you're really
ambitious you could add a good clear coat. Another cool product is a
type of turtle wax that also contains a buffing compound, if you're
looking for a really smooth finish. For a satin or a flat though, you
can buy spray can clear coats that will give you either of those two
finishes.
Whatever you do, keep everything clean including your hands because
even a little hand oil can mess things up.
