its not the powder coating that causes grief it is the cleaning
all types weather it be blasting, dipping or even by hand with zip wheels ect removes material along with the previous finished surface
it wont damage welded areas in any serious way but where you have very thin wall section especially high end butted tubes were they waste away dramatically towards the middle of the tubes you can easily cause holes in the tube if the cleaning process is to aggressive
it is really common problem when paining vintage car panels especially were rust has been removed.
