I have not tried the electrolytic method yet. I am more concerned with preventing the rust from returning and destroying the chassis as it will rust again unless preventative measures are used.

For light rusting or patches I wire brush the rust off, usually with a Dremel brush. Sanding will also work. For prevention and appearance I rub on Tremclad aluminum paint. Note that I am not painting the chassis. The Tremclad is rubbed on with a cloth in minimal amounts. It is 90% dry after rubbing. This gives the chassis a clean look similar to fresh plating if done right.

Heavy rusting gets the severe treatment. Fortunately I find that rust is mainly on the outer surface of the chassis. In this case I remove the critical parts, mask the others including the tube sockets and carefully sandblast the chassis. I then apply a spray called Rust Converter by Rust Check, available at Canadian Tire. This converts the residual rust to a black coating and acts as a primer preventing further rusting. The final finish is Grey hammertone paint.

Not original but in my book paint trumps rust unless you have the means to replate the chassis. Some may use extensive brushing or sanding to remove the rust then use clear lacquer for prevention. This may not look original also.

Finished Philco 51A, sandblasted, Rust Check and Hammertone paint.

The Philco as received.
