protecting powder coat on new bumper/bars
so i live in the salty northeast and have had tons of experience with powdercoated products for trucks all of which end up looking like rusty pieces of S**t in no time. so i was purchasing some POR-15 for the frame and underbody and came upon a clearcoat product they make. my thought was to paint the entire bumper and side bars with the clear coat before installing. however, i have to take some sandpaper to the finish on the powdercoated bars so the clear coat will stick. has anyone done this? am i out of my mind to sand a new product? will the clear coat cover up the scuffing from the sandpaper and make the bars look good again? i do not want a repeat of the same old powder coat issues i have had on every bumper i have ever owned but i am nervous about sanding a perfectly good looking bumper.
