Yeah Might be stupid - but I'm new to this whole building stuff. I molded a plastic/resin fairing for my FW 190 airplane. Well, it needs sanding and the best wood grit sandpaper isn't doing SQUAT to this stuff. Any ideas of some HEAVY duty industrial sandpaper? Would a dremel just be the ideal thing to use? Thanks.

And can someone point me to a good microballoons resin or filler or something? Thanks. Jesse

I would probably just break out the dremel. Just me.

Jesse,
The best sandpaper I have found is "Sandblaster" by 3M. It is available at Home Depot. For filling I like to use "Super Fil" that is available from F&M Ent www.stits.com. It is a 2-part epoxy filler that is very light and easy to sand. Only bad part about it is that it takes over night to cure. Sounds like your filler is about the consistency of a rock--good luck!

What you want is an "open coat" paper. It will not clog as fast and depending on the type of material/grit used can cut through stuff pretty fast.

Try wet and dry paper and use it wet.

I'm not sure exactly what the filler is that your using.

You could try the open mesh sanding "paper" used on drywall sanding, sanding screen. It looks like screen with grit impregnated on the strands. It doesn't load as easily since it falls through the hole. I've used this when trying to grind out odd material.

I think this type is also available in single sheets in different places. It's been a while since I've gotten any.

The finest grits are probably still course enough for what you're doing.
