Your cart is empty.The glass fibers in PrepPen are finer than human hair yet stronger than steel when it comes to cleaning power. The glass fiber cartridge can be extended out by turning as needed, then easily retracted when not in use. The refill is conveniently stored in the handle. Sand paper can be too rigid to directly contact and clean contours of inside edges. Conventional sanding only hits the high spots. PrepPen's glass fibers get into the smallest recesses. Save time and money by replacing folded sandpaper with PrepPen

I've never used a fiberglass pen before but I needed one for both paint chip repair on my car, as well as electronics repair where the boards are damaged. This one is terrific. A little twist, a fiberglass brush comes out, and with a few swipes of the pen rust or corrosion is gone.At this point I'm kicking myself for never having tried this technique, and the Philmore is a terrific product.

I had to remove the discontinuity between a masked place and a newly painted surface on a motorcycle oil tank. It was a 1/8" inside radius I needed to work on. This did the job quickly.

Pen performs fairly well. Provides the necessary sanding and detailing. Only thing is mine came with only one fiber cartridge instead of two as stated on the packaging.

What's to say? It's a fiberglass "eraser". It works. Just be sure you use it outdoors where the wind isn't blowing in your face. It creates a fine fiberglass dust as it works, which is dangerous for your lungs. You might want to consider getting a dust mask before you use one of these.

This prep pen actually looks like a pen. Easy to hold and use. I noticed a few days ago that someone had just touched (with their truck) part of my car bumper. The contact removed the paint right down to the metal. I already had touch up paint, but I know from experience that you have to feather the edges of the exposed section first. The prep pen did a great job of sanding the edges just enough. When I touched the area it was smooth. I applied the touch up paint and you can barely see where the small chip was. This pen is perfect for small imperfections--an inch or less. Highly recommend.

I used this device for the first time repairing rock chops on 2 vehicles this fall. Was very easy to sand out rust and also level down first primer coating. Very useful.
