I am curious then to how well powder coating holds up to extreme bending. Would it crack off if you took a really big hit to a rim, like have to get a new rim hit? Has anybody trashed a velocity deep V and noted the damage to the powder coat?
ive rallied my rear wheel pretty hard, ill post some pics when i get off work later tonight. And yea there is some visible cracking, but you can hardly tell. I wouldnt expect anything different considering its taken some massive hits.
as for proper prepping that is a symptom of poor worksmanship, and for any product, will affect the quality of said work. If you stick to a known brand/PCer the work should be of high quality and you wont experience any of those problems to any noticeable degree.
The PC'ers ive talked too all told me that they first do a sand blast to remove any paint, logos, debris. Then they clean it off and dump it into a special chemical stripper that then removes any further contaminents. Then they powdercoat.
Also anything that cant withstand high temperatures like plastic, some carbon fiber, and glues will melt or become deformed in the process.
