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.

These little grey soft foam sandy sticks are now my staple go to for just about every single surface sanding! I have to say if I had a problem with them it's that they are quite soft foam, if they were just a "smig" denser maybe... but.. but... they're quite amazing! Even though it claims to leave you with a finish around 2000 grit they can be used for just about anything you have to sand. I have never had any need to go lower than 600 grit on my gumpla and usually it's 800 grit for "rough " sanding and then 1,000... 2,000 right to 8,000 to finish off with a dry board eraser.(I just stumbled on this little trick and love the type of finish it leaves on bare plastic models. But... the grey balancers are the go to really. So now I start at gate marks with 800 grit and any swirls or mold imperfections then if it needs a bit more blending I use 1,000 over the entire part(usually it is not necessary.) But honestly for the most part it's just 800 for gate marks and such, right to one of these bad Larry's over the entire part, and finally back to a uniform matt polish with the dry board eraser and that is it!! So, only three easy steps for an excellent looking matt plastic finish that is surprisingly uniform! I have just ordered a few more boxes of these and also the gunprimer gate remover kit! I will be sure to review that product as soon as I find a feel for the new routine. But these are a lifesaver and step saver too!! P.s- I have to agree that they do wear out very quickly as compared to other sanding sticks/ foamies... but I don't mind if they are saving me a bunch of monotonous sanding steps and time!!👌👍👍👍
