I've gone over the Block Brushes before, but haven't discussed in detail the skinz that are available. There are many options to choose from, I chose the "Reaper" which is my personal favorite. Each design comes with 6 separate pieces for each brush that are numbered from 1-6 to easily identify softest to hardest or the other way around. These very simple steps will help you get the best adhesion onto your brush. 

Spray some Moo-Kleen Electronic Cleaner And Degreaser onto a towel and wipe off the top portion of the brush. This will ensure all the contaminants are removed in order to get the best adhesion. After that is completed, apply your "skinz" onto your brushes. Don't forget to use the numbers listed for easy identification of each brush. 

You can use a heat gun if you like to lightly go over your skin after application but it is not necessary. The heat will give it a little extra adhesion to your blocks. 

And just like that, your blocks are easily identifiable with an attitude. See ya at the track!
