Pinewood Weights Car Kit-Derby Car Tungsten Weights 3.25OZ 14 Pieces 4 Sizes&0.5OZ Graphite Powder Lubricant- Cylindrical Weights-Graphite Lubricant for Derby car Pine Derby Car Wheels Axles Speed

I cannot say enough good things about this product. The lock (a deadbolt) on our 1-year old Marvin French doors became unpredictable and difficult to turn, so after reading reviews on this and many other products, we decided to try this even though there were some complaints. The graphite is very dark, and our doors are black painted aluminum, so we weren't too worried about the "mess" some complained of (maybe would have been if the doors were light-colored, IDK). Shook up the bottle to make sure the powder was not compacted (does it compact? IDK) and towards the tip. The tip on the bottle is very fine and went into the keyhole so easily, and I probably injected a little too much because some did back-spray out, causing a small mess that was later easily cleaned up with dish soap and water. I put the key in and turned it a few times, and voila, a perfectly easily-turning lock! It has been about 10 days since product was applied, and lock has worked smoothly and flawlessly every day since then. Sooo happy with this very inexpensive and easy fix, and will definitely use this product on squeaky door hinges, although will take care to protect items (with cling-wrap?) around the hinge from any back-spray, especially indoors.

nice product

Easy to use and worked better than expected

Works well as described. Be careful when using as the powder comes out fairly quickly.

My mechanic advised me to use graphite. Amazon delivered it the next day. The graphite worked in just a minute.

I purchased this to lubricate the internals for lock sets. Container us nicely made with a rubber cap to keep product from spilling. I would definitely purchase again.

I've purchased this for a 2nd time now. We used this in my son's pinewood derby car last year and he won first place. The weight of these is accurate, at least according to my scale it is. We loaded the wheels down with the graphite as well to reduce friction there.

Met expectations

I don't know if it comes from being in our Canadian weather of extreme temperatures and wet weather but I find that with time locks get harder and harder to open. Fearing that I'd eventually break a key in one of them and end up needing a locksmith to let me in I Googled solutions, I didn't want to gunk up the works with oil that might freeze at some point so I decided to try this powder instead. All my locks now work like new again and it's been a couple of months so I'm very pleased with my purchase.

Ignore the "pinewood car" part of the description - this is simply DRY, POWDERED graphite (NOT liquid). Posted photo show size of bottle, which is about 3/4 inside diameter. I'd guesstimate you get about 4 Tablespoons of powder. the powder is FINE and smoothly ground, so works well for lubrication. Bottle appears to be filled to top of label, so ALMOST completely full. If you've never used before, graphite powder CAN be messy and WILL get your fingers dirty. The metal applicator tip is nice, compared to plastic-tipped bottles of similar products. Shipped from Washington State. Received in central Alberta, Canada in 4 days, via Vancouver routing.
