What we have done, with good success, is to fill the edges of MDF and
plywood, which are very absorbent, with lacquer-based automotive
putty. One brand we use is called Green Stuff. It is the last filler/
putty automotive guys use before they spray on the primer. It dries
quickly and sands beautifully.

Now that's interesting. *I have been using Durham's Rockhard for years
on that stuff. *It dries fast, sands very well, but on occasion there
is an adhesion problem with small fills (like large nail holes) in
materials like MDF that tend to be hard and dusty.

Any adhesion problems? *How fast does say, and 1/8" diameter take to
dry before sanding?

Can you put latex coatings on it as well as solvent based?

Have a manufacturer handy?

I am seeing and using more and more of this stuff in different grades,
and frankly, as poor as the wood is that I have been purchasing for
some time I am getting to the point I prefer it. *I prefer the end
product, but don't prefer working with it.

Man, I miss wood. *If you had asked me 30 years ago if I thought we
would be using modified cardboard for baseboards, finger jointed
nastiness from Chile for trims, sheets of termite leavings instead of
doug fir (which I thought was crap at the time) I never, ever would
have believed it.
