Is it chrome-plated? I’ve been thinking of painting my no-name Tiawanese
job, but it’s chrome-plated, and I doubt that regular paint would stick
all that well. Can anyone comment what the would be the best way to treat
chrome prior to painting? I could sand it a little, or wipe it down with
HCl or H2S04; would this etch the chrome in a useful way to increase
adherance?

For sticking to bare metal, the electrostatic heat-cured powder stuff is
supposed to be the business. Does that stuff come in colours? There’s an
outfit in town that re-paints filing cabinets and whatnot using this
method. Maybe I’ll ask them.

If I do the paint thing, it will be green, to match the green Miyata seat
I have on it. (I wish they’d had blue!)

Frame Painting (from thread 32/2/1)

Some frame painting questions that I thought waranted their own thread:

I sanded and spraypainted my 20" and i highly recomend the process… If you dont want the color to stay on for more than a couple of weeks. I should have powder coated! Here is another idea, Bring your uni to an autobody shop, like macco and have them paint it with the same stuff they use to paint cars.

Powder coating would be great for a unicycle. They have several types of
materials that are very tough. An advantage of powder coating is its
ability to build up some thickness on sharp edges. This is due to the
static building up on these same edges. Static charges hold the powder in
place while the piece moves into the oven for curing. A disadvantage is
due to the same principle. It is difficult to get powder into an interior
area. This would be the reason to go to an experienced powder coater. Most
coating shops can etch the surface and apply an iron phosphate to aid
adhesion. One economical way to go about it would be to take the frame to
the coater and ask them to work it in with other jobs. No setup costs this
way. Doing it this way, you will have to take whatever color they are
working on that day, but you could take it home and paint it whatever
color you want. The powder coat would be a great primer.

If I may suggest, there is another coating that may be good for this
application. I work with a few guys that off-road in the big 4WD trucks.
They take their vehicles to the shop that applies the spray-on urethane
bed liners. But instead of inside the bed, they have the lower half of the
truck sprayed. Sounds weird, looks and lasts great.

Cool! I’ll have the lower half of my forks done. :wink:

Now if I can only find a way to hang the mud-flap with the metalic girl siloet…
