   it is pretty aggressive (the basis for most paint removers). When I'm prepping

   for a layup I typically wipe the surface down with MC prior to sanding to

   eliminate surface oils, then sand, then a final quick secondary MC wipe with

   a clean paper towel to remove the dust and anything that might have gotten

   onto the surface from my hands or the sanding tools. At that point the surface

   is the most active it can be and it's ready for additional layups. Follow this
procedure and you'll never have a delam to deal with. FWIW.
