K Tool International 70550 Automotive Glass Fiber Sanding Pen with Extra Sanding Point for Garages, Repair Shops, and DIY, 20,000 + Fibers per Tip, Portable, Black

This item wasn't exactly as I'd expected, but it worked well for removing debris from small paint chips on my car prior to adding a primer, basecoat and paint. The tip on the sanding pen is made of small, tightly compacted fibers which do sand small areas very well. The fibers can break, but I found very little of that when using this item. You have to twist the pen to deploy the bristles. I found that while the pen seemed rather flimsy in its build-quality, the pen worked as expected and it was easy to extend the bristles to varying lengths.I'd recommend this as a tool for those looking to repair vehicle paint chips, or hobbyists who need to sand in tight areas.

I've used this item for many years. Lasts quite long and has a spare refill inside the handle. This new one is a replacement. The bristles retract into the handle when not in use. The brush works well on electrical contacts, and also on preparation of surfaces to be painted (to get down to bare metal, etc.)Additional refills are available.

Wish it was a little thinner, but overall a good product.

Compact , easy to use, works as advertised and refills are available on Amazon . Product paid for itself many times over with the 1st use , saved a trail cam suffering from corroded battery itis .A few minutes of easy work ,turned it from an expensive piece of junk back to a fully functional tool.

WORKS GREAT FOR GETTING RID OF RUST FOR PAINT PREP AND TOUCH UP !!

I bought a used 2016 mustang that someone seemed to have spent quite a bit of time on the freeway with before me, as there were a dozen chips in the bumper (very small, but noticeable since the car is white and the chips appear black).sanding pen made it extremely easy to scuff all the wounds and prep them nicely for painting, without damaging the surrounding areas and making the touch up more noticeable. Would definitely buy another one of these if I have to do more touch up work.Yes, the fibers are brittle and will break off easily..but that's the point. take your time and don't use excessive force and it works very nicely for even really small chips.

The pen does a good job but the size of the tip is gigantic for sanding rock chips on vehicle. Maybe if a pebble the size of a dime hits your car it is fine and leaves a chip the size of a pea then it could be used. I'm not sure why so many makers of touchup items for vehicles can't understand that most chips are much smaller than the products they release. I realize this is a universal tool but automotive was in the description so I'm just venting a little after dealing with this and touchup paint kits that have applicators that are way too big to actually fix the issue without it looking like a toddler did it. I am eventually going to see if I can somehow cut the tip down before use but then that means each time I have to push more out I have to trim it again and that will be a lot of times.It does a very good job at sanding the the clearcoat and paint very slowly and is easy to use, it's the size that is the problem. If it had a tip the size of on one of those round silver ball pin heads then it might be perfect. Like others have said, it is fiberglass and kicks off fiber dust so be wary of wind and wear nitrile gloves and eye protection or pay the annoying price.

Easy to use. Well priced. Used in hobby to clean electrical contacts and small metal surfaces. Suggest to wear gloves, eye protection and mask as this is a glass fiber product which could irritate skin, eyes and nose. Would recommend for manufacturer's stated use.
