Ok.
I have some rasty bubbles popping up under the paint on the rear end alu skin. Some is centered around the center mount for the spare wheel, but other there are other that are popping up at the same level as where the honeycomb trunk floor is, but on the outside (obviously). The weird thing with these bubbles is that there is no steel contacting the inside of that spot, there is just some trimming that I glued on with contact cement.
The only thing I can think of generating galvanic currents there is that I in my stupid cluelessness used standard, rust prone, steel bolts to fasten the rear fenders to the body. These bolts are now quite rusty, but there is no alu skin damage (as far as I can see) where they go through the skin.
So, three questions:
1) Why is this happening?
I live close to the beach with quite a bit of mositure coming in at night. The garage is not heated.
2) Where can I get it fixed?
The worst case scenario is a new rear skin for $270 from Caterham, but I need someone who can rivet and weld it in place and give me a good paint job. Gert, Clark: Any recommendations? Any labor price guesses?
3) How do I stop it from happening again?
Zink attached to the alu?
Tnx.
