Howdy everyone. My friend has had this 1985? Peugeot P6 for a while that he's wanted to turn into a single speed commuter bike but recently gave up on it and turned the project over to me. He stripped down all the components a ground off the cable guides on the frame with what appears to be an angle grinder. I was cleaning up the areas that were roughed up by the grinding and it seems that he ground a bit deeper than the actual braze-ons and into the actual tubing of the frame. It's not that deep, I'd say they're less than 1mm into the tubing, but its definitely noticeable. I'm thinking of filling the marks with JB Weld for aesthetics but I'm wondering will these grind marks affect the integrity of the frame? It's made out of Carbolite 105 tubing which is Peugeot's in-house brand of tubing. Tubing diameter is fairly small, not super small though. Not sure on the thickness though. Any thoughts?
