Softback Sanding Sponge Stick #600

In 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.

How many come in a single pack rather then a set?
There's 2 double-sided sticks for packs in singular grits.

Awesome and easy to use for beginners

I'm pretty new to the hobby and had previously been using some crappy little sanding stick and nail buffer that came with an Amazon kit. I had thought I upgraded fully by buying a Raser, but I guess I made the newbie mistake of not considering dealing with curved pieces. Enter Infini's sanding sponges. These are awesome. I was a little scared with dealing with so many different grits, but a quick tutorial vid helped with that and I used them on a kit today that came out so so nice. I definitely recommend them.

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!
