[Shop-talk] How to remove surface rust over entire car?

[Ben Zwissler]

Agree with the approach below and would add that your local body shop will
have cleaners, conditioners and preps for bare metal.  I bought a TR4 body
tub that had been soda blasted and then left to sit for several years
(indoors).  I explained what I had and they sold me what I needed.  The
first one I applied smelled mostly like what I remembered phosphoric acid
smelled like. The price wasn't bad and I was sure I wouldn't use anything
incompatible with the paint.

If the rust is too much for plain conversion coating, go to Home Depot, etc.

& buy a gallon of phosphoric acid, dilute minimally as directed, and bruch
it on repeatedly.  Scotch-Brite helps in the process, and is better than
most alternatives.  Wear gloves - it won't hurt now, but the rough peeling
skin on your fingers in a day or two will make you wish you hadn't bathed in

it.

When it's clean, rinse with water, towel dry (to avoid flash rusting) and
then apply conversion coat and rinse as directed.
