Quick question: Is it necessary (or even a good idea) to very lightly scuff sand after my first set of three very thin coats of P&L 38 (thinned 50% with MS) wiped on and before coming back about 24 hours later to do my second set? Please assume I have no rough spots, dust nibs, or dead bugs (will scuff if I do). I am just wondering if the sanding is necessary, or at a minimum best practice, for adhesion when I come back and start the second set of three thin wiped on coats.
The first set is now drying, and I will return to it tomorrow afternoon or evening. Your responses are greatly appreciated.
Thanks.
Andrew
