You could try Boston AutoPaint in Lynn, MA.  Talk to Doug.  He takes care of my body work and owns an early VW bug.  Contact me at ddbjorkman@verizon.net it you decide to contact him and I will tell them you're calling.

 Hi Everyone

I'm new to this list. I have had two Vanagons since 2018 (one at a time)
and have been active on TheSamba since before then when I was looking for
my first van. A friend of mine recommended I join because I live in MA and
there are apparently quite a few northeast folks here.

I have an '85 Westy with some pretty serious rust on the rear right jack
point. It appears to be caused by water ingress in the rear right window
seal, which is bubbling with rust. Here are some photos of the jack point:

You probably noticed that a previous owner sprayed in expanding foam
insulation and put bondo over the rust. I will have to scrape all that off
to see the full extent of the damage, but my amature diagnosis based on
what I see so far is "not good." I'm worried especially because the
trailing arm mounts to the jack point.

I took it to a couple local auto body shops last week and they both
declined to work on it. Can anyone recommend someone who might take this
on? I'm in Acton, MA.

Thanks!
