Advangates or disadvantages of powder
coating over conventional acrylic enamel
February 14, 2007
I'm restoring a vintage motorcycle and want to know if it is
better to powder coat my frame and other associated parts or use
acrylic enamel. What would be the advantages of one method over the
other?

Powder coat has superior bonding strength. It bonds to the metal
in the heat stage by " sinking" into the grain structure of the
metal. powder for years had a bad reputation of orange peel effect,
because of this. paint has to have a primer to use as the bonding
agent. today we can sand powder to make the surface much smoother. we
have bike frames with over 30k. on them

It seems that a restoration would require a paint type and color
that was originally used on the bike. I'll bet you can find a
supplier that makes a paint for this application. (Hint:the original
paint isn't powder)
If you're not restoring but just want the frame painted don't use
powder, the prep-work is very involved and if it isn't done right
you'll be wasting your money. All you have to do to wet paint the
frame is degrease it, sand it smooth, prime it and paint it. Also,
with wet paint you can keep some matching touch-up around to fix rock
chips and other blemishes.
