IMO,
Poorboy's is a great one-step product
Duragloss 501 is a cleaner polish. You may want to use
Correct, I used 1 part 601 to 4 parts 501. Then 1 pt 601 to 4 pt 105. I waited about an hour between those two. According to duraglosses formula of humidity divided by temp times 60 i should only need an hour to cure before wax, but ive seen many people say 12 hours so i figures it wouldnt hurt to wait the 12 hours.
If you're looking for something easy to use, resonably priced and very durable you can't beat Duragloss 105. Mix it 4 parts to 1 part with DG 601, apply a thin coat wait for it to haze and buff off. After a couple of hours you can add a coat of DG Aquawax spray for a great durable look
