The recent thread on the bubble flare tool reminded me. I'm fascinated
by specialized tools. There always seems to be a specialized tool, for
just such a situation. The tools often aren't cheap, which makes it
hard for a casual tinkerer to justify the cost. However, when you have
the right tools, jobs go together so much faster and easier (which is
why the tools were created in the first place.) You might find that
some tools are even rentable.

Something to consider on your next Vanagon projects...
