So, I have a 19 JLUR, and I have 2 door hinges that are starting to bubble. Seems to be a pretty common thing based off of my research. My question is, how many of you have left it alone? I'm not a fan of repainting a vehicle. I'm covered for 5 years with unlimited miles. I'm thinking I should wait till it gets worse, or more areas start doing the same thing. I don't want the thing painted 20 different times. Plus, how fast does that really spread? I know rust can mover pretty fast, but how quickly does this spread? My next biggest problem, is no body shop near me is really setup for Aluminum. Should I take to an Audi body shop? They have a lot of experience with Aluminum, or at least take it to a Ford Certified body shop. Thoughts?
