Should you graphite the wheel tread on a pinewood derby car?
Dry lubricant is the only allowable lube by standard BSA rules. Graphite is a dry lube and it will not dry out. Do not mix dry and wet lubricants. They will not work well together. Although graphite does not dry out over time, it can in fact draw moisture from the air it is exposed to over time. This all depends on the humidity levels of the air that the car/graphite is being stored in. If the graphite draws moisture it will start to act like a paste and slow the car down by placing more friction on the axles. I always recommend re-graphiting your wheel just before any race.

What is a better for pinewood derby cars graphite or oil?
First and foremost go and check your rules to see what lubricants are allowed or disallowed in your race. Many rules will usually allow one lubricant to be used, but not the other. The last thing you want to have happen is to be disqualified for using a lubricant that was not permissable by the rules. This question is a very big debate in the Pinewood Derby forums. Most seasoned Pinewood Derby racers will probably go with a light oil such as NyOil or Krytox 100 (by DuPont). I've even seen instances where 3in1 oil or WD-40 have been used successfully. However, on the graphite side, a lot of changes have taken place in the last couple of years. The old Tube-O-Lube and Hob-E-Lube brands aren't the graphites of choice any more. Serious racers now use a much finer and purer graphite that has longer lasting capabilities. Some are even pretreating there axles (NOT the wheels as they can melt the plastic in their wet form) with more advance formulated spray lubricants, such as SailKote from Team McLube. These new spray lubricants contain different forms of Krytox (such as Krytox 102). They are still considered dry lubricants, but when used in conjunction with purer graphite, they are equaling and even besting the speeds of the oil compounds. Then their are some who have found breakthroughs of certian oils and graphites mixed together that are astounding the Pinewood Derby communities. To learn more on this, go to Google and search on the words "Pinewood Derby Physics Lectures". The first link up will take you to Doc Jobes Pinewood Derby Physics Lecture pages. Check out Lecture 13, the results are highly interesting. A few years ago, your question would have been an easy one to answer, as the newer lighter oils available were far superior. Today, that's just not the case anymore. My recommendation is to follow your rules and if you are allowed to use any lubricant go with what you know works for you. You'll be much happier with your results that way. Personally, I lean towards the graphite camp, but when it comes to lubricants I always keep an open mind.

What kind of paint should you use on a pinewood derby race car?
Actually any kind of paint can be used on a Pinewood Derby car, as long as you take the time to let it dry properly. Now some paints do not stick directly to wood very well or soak into the wood requiring several coats. In this case you need to paint the car with a primer paint first, then paint the car with the paint of your choosing. Also when wanting to put a glossy shine to your car, you need to be very careful of the sealer you use over the paint. Not all sealers and paints are compatible, and I've seen sealers ruin very good paint jobs in the past. The best method for all paints is to test them on a piece of scrap wood first to make sure they are going to produce the desired look. If they look good on the scrap wood, then they will most likely look good on your Pinewood Derby car.
How does cetaryl alcohol dry the skin?
it doesnt, it is actually a lubricant!
What is dry carbon lubricant?
Dry carbon lubricant is a type of lubricant that contains solid carbon particles suspended in a carrier fluid. It is applied to reduce friction between surfaces without using oil or grease. Dry carbon lubricants are often used in applications where oil-based lubricants are not suitable, such as high-temperature environments or where cleanliness is important.
What is the difference between dry film lubricant and solid film lubricant?
Depending on the context, they usually are referring to the same thing. In some cases, people refer to air dry solid film lubricants as dry film lubricants. For more information check link.
Where to get graphite?
graphite as a dry lubricant is sold in powdered form in most hardware stores.
What are the advantages and disadvantages of graphite?
An advantage for graphite is that it can be used as a dry lubricant on electrical appliances.
What are examples of lubricants?
A dry lubricant is a material that is able to reduce friction between two surfaces without the need for a liquid-based lubricant. Examples include graphite and molybdenum disulfide, the two most common dry lubricants, but hexagonal boron nitride and tungsten disulfide can also be used.
