Powdercoat chip rust

[Yzfguy]

Sorry if this is in the wrong place....
I have a small chip in the powder oat on my bumper. It has some surface rust and I'm wondering the best way to repair it to stop the rust.
It's a small chip, so I can't really get in there to sand the rust off, so do I actually sand a larger area and touch it up with some Rust-Oleum paint? Any suggestions appreciated ( besides " get used to it, it's gonna rust!")

Might try that chemical you can get at auto parts store. Completely escaped me while writing here, it mixes with the rust and oxidizes it or something.

LOL I will go find the name, I totally lost my brain writing that.

Corroseal, it is expensive though about 30 bucks a quart. But it works well, there are others out there also.

buy some ospho to convert the rust and then touch it up with something durable.

So you just apply it, no need to sand or otherwise remove the rust? Sorry if I sound like an idiot.

if it's just surface rust the ospho will convert that to a paintable surface. sanding is never a bad idea before painting anyhting, but if it's just a little chip. dab that on and then just use a small brush with some paint in a dixie cup. Without seeing the chip I can't offer more process specific advice than that.

It's tiny... Like half the width as a pencil eraser. It's a new bumper, so it's only surface rust, but it's kinda deep in there because of the surrounding layer of powdercoating. So I can't get in to sand it unless I make a bigger mess out of it.

I used one of these: https://www.amazon.com/dp/B00144895O?psc=1&ref=ppx_yo2ov_dt_b_product_details

Spots I couldnt get to I sprayed with this: https://www.amazon.com/gp/product/B0009X8LPE/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1

Once that dried i used this: https://www.amazon.com/gp/product/B003CT49B2/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1

This - chemically seals it.

That's so small I'd just neutralize the rust and dab some black paint in there and call it done.

They have several rust removal, rust neutralizer, and rust prevention products.

Just ordered a kit. Thanks!

Thanks, guys. Today I applied the POR15 kit.
Little more involved than I thought it would be, but I feel like it's good to go now. The etching chemical is amazing, it literally removed any bit of rust and I feel like it's sealed and protected good now. Time will tell
