Im not slamming anyone here, but these things rust BIG TIME. I have seen some that look like they have been in salt water. I have told others to use a product we use on our salt water outboards called corrosion guard to keep the rust off. Any others have a solution?

Scuff it off and spray a few coats on clear on it. I know Bud Bartos does that with his retro chassis to keep them looking good. Should work against rust or tarnish.

All steel wing car chassis rust. Be sure and use some alcohol and swab it down after soldering in the motor. After racing take motor out and clean everything up. Just a normal thing.. no big deal. :good:

Non-plated always require more diligence, both cleaning them thoroughly after building, and keeping them clean afterwards.

After soldering in a motor, you need to swipe down the whole motor box area, from the fumes and splatter.

That said, the chassis has been a big hit, and the first batch has sold out.

The next batch will probably get plated, and of course, the price will be slightly higher.

Living in Florida doesn’t help the rust issue. Keeping it in a plastic bag between races helps.

Personally if I lived in a place with high humidity I would purchase an electronics digital dry box storage cabinet.

Wash it with baking soda and water than put a coat of Gun Blue.

That worked for me.

For soldering in motors, once I have tinned the motor and chassis I use a liquid rosin flux for all future motor installations. I bought a bottle on eBay and transferred it into an empty nail polish bottle with a brush in the head which I also got on eBay. That helps a bit with the rusting from soldereing in motors. It will also help on plated chassis where the acid flux can start eating away the plating. it is a must when soldering a motor in an aluminum plated chassis too. As far as rusting in general goes I use copious amounts of elbow grease. I was born with some and have yet to find the need to buy more. I would gladly pay more for a plated chassis. I have some old Koford plated EDM chassis that are 25 years old without corrosion.

I always scrub a blued steel frame in "barkeepers friend" before cutting the parts off the tree and soldering them together....and after soldering as well.  Armature dye or nail polish also seals the bare steel, and shows cracks and rub areas.

Kofords are plated. I have some with a copper and maybe nickel? Some of the nickel has worn to show the copper underneath

I buffed mine out with some small scotch bright wheels. Birchwood Casey Barricade is a great rust preventive, found in any sporting goods sections.

Soft Scrub with bleach and a Scotchbrite or stainless steel and or copper Brillo pad also work great. Using a wire wheel or steel wool will only create more rust.

This. Rosin flux is much less corrosive than acid flux.

Perma Blue. You can get it at Big 5 or any gun store.
