Once a month I get an injection in my sinister (left) eyeball for a retina anomaly.  I ordered the doctor to give me the needle.   Although it feels bigger, its 0.3 mm in diameter.  I used it to squirt water into a wing-leading-edge dent, then heated the area with a lukewarm MonoKote iron.  The dent came right out, and the hole is nigh invisible. 

  there are a few suggestions for dent removal in the article in the April, 1992 issue of Flying Models for a smaller model called "The Professor" by Mike Spedaliere and several other wood working hints for better looking glue joints and parts fit up. I'll have to get that out and refresh my memory. I think one old school way was just lay a dame rag on the spot, let it soak the wood, and then apply the heat from the iron. I can't remember if the damp rag is left in p lace or not. The key in any method is to soak the wood and make it swell up.

I guess I could have sanded off the finish to get at the bare wood, but I took the easy way out.

   Well, you didn't give us that tiny detail that it was a finished model!! I'm glad it worked for you but if you had not acquired the needle, a steaming wet rag and the iron may work also.

Injecting through the paint and using low Temp heat is a clever twist.

What is the procedure for removing the bump from overdoing the removal? 

Now I need to look for .3mm holes in Howard's wing LE. Let's see...that's .0118". Shouldn't be a problem with my 30X loupe...but which ImpAct?  Steve
