Hi – I have a new aftermarket jeep bumper that came powder coated black. I live in the Northeast and I’ve seen rust come up through powder coated metal after a winter or two up here.
Is there a semi-gloss clear topcoat that I can apply to seal the pores in the powder coat? If I use a satin clear coat spray (like Eastwood 10300Z), will it stick to the smooth powder coat surface and do the job? I’m looking to keep my bumper rust free for a long time – I’d appreciate any advice.
