I wish I had this product sooner. It looks like just an unassuming grey block, but when you use it on a piece that has been sanded with 600 or 800 grit sandpaper/sanding stick/glass file, it brings the surface right up to about an 1800 or 2000 grit. Used in combination with the Balancer White, and it drastically cuts down the time I spent on removing gate marks. Giving it 4 stars because it does seem a little fragile along the edges. So far, I have finished the last half of one RG and a complete RG following that. As you can see in the images, the edges of the both balancers are a little frayed, and I find myself exercising increased levels of caution and avoiding touching that part of each one. (assuming the images did upload correctly. I have attempted to attach them, it said it went through, but they don't appear as I type this)

Honestly a a great little sponge that can do a lot of heavy lifting. You can use it for the second step in gate removal after the razer, or for scuffs and minor scratch marks. You can also use it for more detailed sanding as well, after 400 and 600 grit without having to bust out other grits like 800-2000 if you're lazy. I like matte looks so I usually finish with the green side from the white balancer. Needs cleaning every few pieces with some tape, and I think one sponge should last 1-2 kits with heavy use.

I honestly always made snide remarks about Gunprimer and their pricing etc, but slowly and surely I've tried more and more of their products. This one right is at the top of my list. I'm currently on my third kit with the first balancer I took out of the pack and it's still going pretty strong. Makes it's easy to use a higher grit to get rid of the nub and be able to come back with this and almost only need a single pass.
