With a fly cutter for me.

bout an 1/8" at a time with my surfacing bit. By then it usually only takes a couple of passes. A lot of dust!

Standard MDF, sealed has always worked for me. The base sheet under it has lam liner on it so I don't have to worry about it bleeding air. Just scuffed up the liner and put the plenum down on it with contact cement. Surfaced plenum, sealed with shellac, scuffed the top, and after skinning and flipping spoilboard used Titebond. On the other hand, the one I have now is only the second one in 5 years. Others may have tried different combinations more.
