Tire rub rehab. Suggestions?

[Justin]

Sunday I found myself trapped on a 12 mile stretch of sticky trail of gritty mud. Had to stop numerous times to clear my brakes and stays of mud so the wheels would keep turning. Once home a cleaning with the hose revealed four spots on the forks and chain stays taken to bare metal from just the one ride. Now I know what you are thinking but look at the photos included showing plenty of clearance. 

Any suggestions for treating the bare spots? Not at all concerned with cosmetic appearance just want to protect the metal from rust and what not.

thanks for reading!

Mask and rattle can it with some primer? You can make interesting shapes with the masking and have some fun with it.

Exactly the same thing happened to my seatstays last week when my rear Big One flatted catastrophically and I walked almost 5 miles home with wholly flatted tire rubbing the stays (plenty of clearance for inflated tire, but deflated tire was completely flattened against rim and consequently spread out to max possible.

I cleaned, masked, then put 2-3 coats of acrylic primer and 2-3 coats of crimson acrylic because I had them lying around, to contrast nicely with the frame’s British racing green powder coat.

The lug detail on my seatpost tube was chipped to bare metal, so I used model paint to repair it. 

I mixed up a small batch of Appaloosa Mustard by mixing Testors GI Yellow with a tiny bit of Gloss Black. I then painted small swatches on a piece of clear plastic so I could hold the paint sample against the frame and judge the color. If the swatch was too light, I added a tiny bit of black; if the color was too dark, I'd add a bit of yellow. I went back-and-forth until the color was correct.

After I matched the color, I gently wet-sanded the area with 400 grit wet-or-dry sandpaper, and cleaned up with water. (Don't use alcohol, bestine, paint thinner, or other solvents--they'll blunt the clearcoat.) I let the area dry, wiped it with a tack cloth and a blast of compressed air, and repainted with a small brush.

Imperfect, sure--but it's better than bare metal!

My trusty 2018 Riv Catalog - which I inexplicably have four of - says you can use Sally Hansen's clear nail polish. Actually it says you can use fuschia, too, cuz they're crazy and would do it on a blue frame, but clear is good 👍

Thanks for the replies and suggestions folks. I'm quite reluctant to attack the spots with spray paint but may try something less aggressive.

Clear nail polish is all I apply wherever I have paint missing. I've tried to color match nail polish but then you're in the same boat of wasting money on "trying" to match the paint. Nah ... the clear is great as it "preserves" the spots which of themselves are unique markings that certainly don't need covered up.

I'd second the nail polish suggestion, but I'd suggest some approximately matching colour rather than clear, as it will be easier to see if/when that gets rubbed off. My Romulus came back from being ridden by my nephew with a few scratches through the paint on the frame. I just cleaned those areas with Isopropyl Alcohol, dabbed on some nail polish, and the polish is still in place and doing the job over a dozen years later.
