I'm having my forks rebuilt, and while they are apart I was going to have the lower legs powder coated (the aluminum part) to clean them up. They are sort of bubbling and are stained from brake dust. My problem is that the owner of the shop cautioned me that it may damage the forks because the steel tubes are pressed into the aluminum, and when baked in the oven may cause an issue and cause it to eventually leak. The powder coater said he's done hundreds and never had an issue. So I sort of don't know what I should do now. What do you all think? They are powder coated from the factory, so I would think it is ok, but then again maybe they are pressed together after powder coating...
