Powder coating or painting what's your opinion Options

[TonyA]

When installing fasteners on powder coated items I notice that the powder coating can crack and peel off at the fastener contact. Would it not be better to prep the metal with sand blasting etc. as with powder coating and spray a good etching primer or galvanizing primer and then top coat. When installing fasteners on this application there is not as much damage to the surrounding area. just MHO

Never had this issue as its simply too expensive in my small town ,local place charges the earth because they are geared to large runs of alloy powdercoating for window frames which they do in bulk.
It has great benefit on suspension parts as its tough and resists stone damage,my under car bits have held up well using "old fashion" enamel and was done a long time ago .
