[Hallicrafters] Wrinkle Paint

[Paul Daulton]

Blasting with beads or other media is invasive. Better choice is CO2 
blasting, check local area for vendors. 

Rust removal products do not work with chemicals unless the item is 
degreased. A process popular with antique car restorers a few years 
back was to soak the item in tri-sodium phosphate(heated solution). 
This will remove the paint effectively and prepare for rust removal Do 
not use this process on aluminum. Tri-sodium phosphate is sold at most 
paint stores. A couple of teaspoons in a coffee can of water will bring 
paint brushes back to life overnight. 

An electrolytic process with ARM&HAMMER detergent is popular with some 
gun restorers, and Shopsmith and other tool restorers. A large plastic 
garbage can is used with a stainless steel anode. A variable dc soource 
is recommended. Google ARM&Hammer rust removal. 

Evap-o-rust is a very good product for rust removal. A bit pricey it is 
sold at auto parts stores. About $8.95/qt and $22.00/gal. Google 
EVAP-O-RUST. I used it for restoring 4 Shopsmith machines and 
accessories in the last 5 years. 

I havent tried it but Kool-aid is supposed to be good as are carbonated 
beverages. The carbolic acid and citric acid works well on rust removal. 

Radiator shops and engine shops often have vats to remove paint, rust 
and grease. May be a bit harsh for
radio cabinets. 

I am just about to start on the spare cabinet for my SX-43. I will 
strip it with auto paint stripper and take it to a friend who has a 
large tank set up for the Arm&Hammer process.
