Yayyy sanding is always so much funnnn /sarcasm. I think I'm going to take the bumper apart, get the bottom metal half sandblasted by a friend, while I'll just sand down the plastic top piece myself. At some point, someone replaced the chrome bumper that came stock on my truck with a stock bumper with (what I assume) was color-matched on the bottom half, but the paint didn't last thru being chipped away, because it had multiple holes with rust poking out when we bought it.
If the peeling plastidip thats on there now isn't enough, I couldn't handle something with more investment peeling off like the 15 dollar temporary solution I bought 6 months ago. I've been looking everywhere and quite a few people have had some success while using primer so I'm probably gonna end up with primer lol
