Softback Sanding Sponge Stick Full Set #220-4000

Out of stock

Unlike regular sandpaper which is prone to wrinkling and tearing, the cushioned sponge backing of Infini Model’s Softback Sanding Sticks is designed to follow the contours of your project beautifully, resulting in a finer finish in less time. Using an advanced manufacturing process, Softback Sanding Sticks abrasive grains are adhered to the backing with an electrostatic charge, providing a uniform sanding surface and longer life as compared to typical sandpapers which are uneven, inconsistent and held together with glue. Plus, Softback Sanding Sticks can be used for dry or wet applications for maximum versatility. Each stick is double-sided for twice the life, with a semi-flexible plastic backbone in the middle for a firm grip and added pressure when working in confined areas. Set of eight 6-3/4” x 1-1/8” double-sided Softback Sanding Sticks includes one each 220, 400, 600, 800, 1000,1500, 2500 and 4000 grit. 2-pack refills of each grit available separately. For even more applications and finishing options, see Infini's Softback Sanding Sponges, in grits from 220 to 1500.

How many kits do these last before wearing out
Depends on scale and parts count. Should last multiple HGs

Whats the difference with these sanding sticks and the premium ultra-precision ones.
These are softer and larger than the precision sanding sticks. These are better suited to large and curved surfaces. The precision sticks, while not small enough for tiny crevices and pieces, is better suited to handle medium-sized areas and relatively flat surfaces.

Better than most

Sanding sticks were a bit bigger than I expected, making it harder to sand across certain pieces and surfaces, but overall they feel much sturdier and easier to use compared to non sponge sanding sticks. 4000 grit leaves a bit of a glossy shine

Best sanding sticks ever.

I have tried alot of sanding sticks, and by far these are the best. These last a really long time as long as you don't use them roughly. Cleaning them off by running them under some warm water makes the last last longer as well!

Does the job

I wish they weren't so large, because I have to switch to a smaller set of sticks when sanding near corners or crevices. Still, these are usually the first set of sticks I reach for, and do the job without issue. They're durable and effective, and have held up for many builds. The 4000 grit stick tends to leave a somewhat oily looking surface instead of a uniformly polished one no matter how I sand, so I tend to not use it. The other sticks are great.

nice sanding sticks

To some point, I wonder if nail files would be better, but then a nice pack of 220-4000 grit comes in, and I'm always amazed I can go from scratches to a gloss finish when using these things correctly. my only complaint is that they're a bit too large for HGAC, and maybe better suited to larger models. if they were half the width, that would be better.

Awesome tools at an affordable price!

I picked up the full set. I'm a bit new at the hobby, and always been a little nervous around subtractive tools (cutting tools, sanding etc). These are great! My favorites are the higher grit sticks (800-4000). I've been using them with my Gunprimer Raser when either the Raser is too big/awkward to use, and to get a final finish that I'm happy with. Raser or a high grit sponge to get things roughly smooth, and a few swipes with the 1500, 2500, and 4000 and the parts look great! Glad I picked up this set!
