doping a wing

[Bootlegger]

  A few days ago I doped a skinned foam wing, and dropped the thing on the floor/ground, what is the best way to get the crud off the wing?  Thanks

[Tim Wescott]

What sort of crud?  If it's sandable crud (household dust, balsa dust, and balsa shavings) I'd be tempted to brush it off as best as I could with my hand, paint over it, and sand the mess flat.

[Bootlegger]

   Tim, so much is crud that you find on the floor of your shop, dust, balsa shavings, just crud, I am gonna try to brush as much off as I can, then go from there, thanks for your reply..

[Tim Wescott]

Unless someone else weighs in I think that's the best you can do.  If the crud is just dust and balsawood, then it should actually sand pretty well.  My worry in my shop would be metal shavings or large sand grains that would roll under the sandpaper and make big scratches -- but even then I think the only way to find them would be to give it a whirl, and maybe pick the offending nuggets out with a pin under a strong light.

Do brush off any cats or small children that may be stuck to it, though.

Put a coat on the top and lay the wing upside down on the floor.  Now finish over it and tell everybody that they are a new form of vortex generators.

My last contest design before my great trip into the wilderness was names the "Surveyor"  It was named that because of all of the benchmarks on the wings.

Try 75% thinner 25% retarder, soak a rag and wipe it off.

   Block sand it when it is completely dry. Coating over it may trap some stuff that could come back to haunt you later. Just block sand that first coat completely off and wipe down with a tack rag.
  Type at you later,

  Guy's, I sure do thank y'all for the reply's, I let it dry for a few days, sanded it, then today I doped it again, gonna let it dry over night and see how it looks, most of the crud sanded off.  Oh, didn't find any small children or other animals any where on it..  LOL

... then today I doped it again ...

The first time around I read that as "then today I dropped it again".  WHAT??.  The I re-read it -- it sounded much happier the second time.

I do that all the time.
