Lots of people use paint powder, but (tongue in cheek) it does adds weight. Using something that's easy to touch up is wise.

never use powder on a race frame , it hides the cracks and is murder to get off !

Powder was never on the cards for that reason of cracking.

Only time will tell how abrasion and chemical resistant it is aswell as repairability but i'm sure that time will come.

Is that true that you find powder coat (when properly applied) is more apt to conceal fractures? I would think paint (normally a few layers thick) is far more likely to flex as a coating and not show a crack... I have seen powder coated structures that show fractures at joints (welded and pressed) but never would have thought of it as a treatment to be avoided.

Certainly a single stage paint is thinner than built up layers. Or is that racers normally only apply a single coverage of color and abandon the primer, top coat for weight savings?

Most of those 2 stroke vibrators Simon raced will develop cracks in the rider!  ;D

Joking aside, checking for cracks is imperative, but weight is also an important consideration.

The low cost and ease of touchup, on top of being able to check for cracks is the reason race bikes are painted. I can touch up my frame for a couple dollars in the event of a get off vs stripping the whole thing to have powder stripped and reapplied.
All you gotta do is do what you gotta do.

i was cracked long before then brent !
back in the old days when men were men and had to race manx nortons over cobbled streets wearing a overcoat  frames were never painted .
and i must admit a well made frame left unpainted with just a light coat of oil for protection does look great . pain to keep it from rusting mind .

I only keep my cracks unpainted to see how they develop over time :)
