Removed OEM spoiler, need advice on how to blend paint under spoiler??

xtrozero · 10-11-2024, 09:02 PM

Hey y'all,

I removed my OEM spoiler as I'm replacing it with a carbon CS style spoiler, and after removal there was a lot of caked on dirt pressed against to the 3M tape where the spoiler/dirt was covering. After cleaning it up and getting the tape off, there's a pretty clear mark where the spoiler was. Is there any way I can make this look a little cleaner? It'll probably be covered by my new spoiler, but just wondering if there's anything I can quickly do before then. Is polishing my only option?

You could try a paint cleaner or polishing by hand to remove the stubborn dirt, but you might require a machine to make it "disappear." No big deal if the footprint of the new spoiler is the same.

Just went through this myself. 3M adhesive remover. The dirt is likely sticking to the remaining adhesive.

I'd wet-sand this with 2400 then buff for a quick fix. This is nothing at all, 15 minutes tops.

A little bit of clarification.

If you have adhesive residue I'd use an eraser wheel + drill on it, which is what most guys will use.

Once that's done you can wipe it off with some bug/tar remover, I use PPG 330, but you can use whatever you like.

I would then use wet-sanding to remove any imperfections, and I'd start with 2400, maybe have to move down to 2000, then go up with it until it was super smooth before buffing.

This guy buffs with power, but you can do it by hand, no problem at all. Watch this video and you'll be an expert, it's so easy.

This can be done in 15 minutes tops if you know what you're doing, but if you don't it could take a bit longer.

The only thing is, most guys don't have several grits of sandpaper, PPG 330, buffing pads and compound laying around, so no worries if you want to take it to a body shop, it'll be quick work for the, but CERTAINLY doesn't need anything repainted/resprayed, just an adhesive removal, clean, sand, buff, and it's ready for the new spoiler or none at all.
