One thing to consider. What I did was rough the track in first, pack it, then put the Durasoil on. Since it was already packed the Durasoil couldn't penetrate. For the next rebuild we will form the jumps while putting Durasoil into the dirt mixture, pack it, and then the Durasoil can penetrate 6 inches. Here is a video of the track.

Makes the track like concrete. It comes in a huge $500 barrell but you only use $100-$150 if you were to build it with the Durasoil, and $75 if you wanted to put it on top. Only thing bad about putting it on top after packing is that when cars nosedive into the jumps, it rip.s It literally feels like elmers glue with more traction than concrete. Blue grooves up great and you never water the track.

Sounds like a surface that eats tires.

It does, but the track doesn't require a certain tire. The video was taken with bald Proline Revolvers. When the track is swept you would run balds, but on a normal practice day with a very fine layer of dust on the top you would run a practice tire with very little tread. For example, I run I-Beams in the front and City-Blocks in the rear with about 10% tread, and they are every bit as good as they were when I first used them on the track (50% tread), and they will be just as good when bald. Tire combo might sound weird, but I did that to prevent traction rolling and smooth the steering out on my Losi 2.0, works great!
