wheel wax

Post by davet » Mon Aug 14, 2017 7:31 am

We're sponsoring a derby race at our church in Ocober and building the cars onsite. I know of Liquid Glass and other vendor-specific wheel bore polishes but I'm wondering if there's a cheaper alternative I could buy and supply to the kids. I'm thinking something like McQuire's #26 or similar. We're not aiming at building the ultimate super speedster just getting kids together with adults to build something.

Is carnuba good or bad for wheel bore polish?

I never had any luck with it using oil, never tried it with graphite.

You mean the carnuba waxes?

For graphite, I don't know that a wheel wax is terribly important. If you're using graphite, I would just burnish it into the bores with a polished metal rod and leave it at that.

For oil, you want some kind of oil-phobic coating on the bores (as I'm sure you know), but I've never heard of anybody having any luck with carnuba.

Synthetic waxes work well, but there's two problems: One, they take a long time to cure effectively. Two, they're pretty nasty stuff if you read the warning labels on the bottle.

Pony Express over at PDDR turned me onto an alternative, that is less toxic and actually works great. The "secret" is Max-Pro Heavy Duty Silicone.. You can use this stuff on the axles in place of Jig-a-Loo (and it is far less noxious than Jig-a-Loo), but you can ALSO use it on the bores.

Max Pro won't eat bores the way that Jig will, but there IS a small amount of propellant in the can that could be hazardous to the polystyrene wheels. So, what you want to do is this: Put some fluffy pipe cleaners (or no-scratch applicators) into a paper cup and spray them with the Max-Pro. Wait about 10 minutes for the propellant to evaporate, then use the pipe cleaner to collect the accumulated silicone and use it to coat the inside of the wheel bores. Wait another 15 minutes or so before you insert your oiled axles.

You wouldn't want to snort the stuff, but it's inert enough that you can spray it indoors without getting a fumes headache. And it really does work well.

I've heard of the MaxPro but never looked into it. So you DO NOT polish it with a clean pipe cleaner?

Side note, I acquired a can of Jig prior to our last race. First time ever using it. I noticed when I sprayed it on that it appeared cloudy as if it had millions of tiny bubbles in it or something else. It also seemed pretty thick. The 3M Dry-Type Silicone I've been using for a few yrs goes on crystal clear and is very thin. I was leary about the Jig and took it off in favor of the 3M. I know that Jig is the recommended coating but I was a little gun shy with it's appearance.

You still want to do all proper bore polishing before you use the Max-Pro. I usually polish with Novus #2, using either a pipe cleaner or a tamiya swab (or both). Then I clean it with Blue Dawn and blow it out with canned air to make sure it's dry and lint-free before I add the Max-Pro (or wax, if I'm using wax).

Re-reading this, I wonder if you meant the post-haze buff you need to do with wax? This is not needed with the max-pro.

For what you are planning for the participants I wouldn't do anything to the wheels other then putting graphite in the bores or a drop of oil on the axles. Your vast knowledge of building a fast car is going to work against you. To borrow a phrase from Larry the Cable Guy, "Git Er Done". Children have a very short attention span especially when it comes to doing boring stuff. Children love to paint their cars and decorate them. If you are able you might like to show the racers the movie, Easy Pinewood Derby Car Wins using science. It's about 15 minutes long and Mark Rober has the personality to make it interesting. Keep it FUN, FUN, FUN.

For going cheep for a bore prep with a graphite lube! Polish the bores with Crest or Colgate whiting tooth paste.

The kids will have fun with this one.

For oil lubes try out the black fire polishes
Wet diamond at Walmart or Autogeek on the web.

Good luck with your work shop davet!
