One word: powder-coat.
The powder-coating process requires that the frame be sand-blasted
inside and out. This will not clean the inside of the frame to bare
metal, but it is as close as you can get.
Use compressed-air to blow all the grit and scale out.
Powder-coating will reach the interior of your frame now because
the powder is applied under pressure, but because a charge
is applied to the frame, and an opposite charge is applied to
the powder, so the powder is attracted to unprotected metal.
I've looked inside (as far as I can) the rails of my frame, and it
all looks like it was covered. The cost for blasting and
powder-coating was $500.
If powder-coating is good enough for the legs of North Sea oil
rigs, its good enough for my garage-babied TR6. I expect that
this car will outlive me, by a lot!
