I've been reading this lately and I just wanted to test this out on a spare door I can get from a junkyard. The only problem I am having is wetsanding, now I understand the grits and spraying down the paper, sanding, then cleaning with the shammy and clean water. But how deep do you want to go when you actually do your first 2 coats then resand with a higher grit. Also I've seen some forums about wetsanding and they said to use soap with a bucket of water, but dont specify on what kind or if it helps / worsens, the situation. 69Charger or anybody else wish to enlighten me?
Thanks
