Subject: gas tank cleaning & sealing

Hi,
I have a freshly rechromed tank that needs cleaning and sealing inside.
Does anyone know of a shop on the east coast that does a good job. I
realise this should have been done before chroming. Obviously I'll need
to talk to someone about what can be done to preserve the chrome while
cleaning. The closer to Florida, the better, but I'll ship it to the
right company.
Fingers crossed.
Thanks
Ray
