Default Aluminum radiator repair this winter.

Well, with winter coming in hard, I may be putting the car into winter maintenance mode very soon.

One of the first things on my list is to get my radiator fixed once and for all. It is a Ron David radiator and it's been fixed once before but I think they only fixed the one tube they knew was leaking. I developed another one shortly afterwards but just didn't want to ship it back to Arizona again so I rather just have it done locally.

I'm thinking of using "Advanced Welding" in Mountain View since they've repaired a hole in my old cylinder heads a few years back but wanted to see if anyone else has recommendations for other shops. Have to really know how to weld aluminum, especially the thin tubes, and do pressure tests ( 16lbs or greater pressure; don't know what they use to be honest). And of course, a guarantee of their work for at least 30 days.

In the worst case, if they simply cannot fix the offending tube(s), then to simply seal it up on both ends. It's got more cooling than I really need anyway so I won't miss it.

TIA
