From Jason @ Deep Gloss Auto Salon: Duragloss 501 marine polish, then 1 part 601 bonding agent mixed with four parts 111 clear coat, then AquaWax.
from rwight: "105 has light cleaners in it, 111 has no cleaners. 111 is also a little finicky with humidity in my experience. 501 can be used as a paint cleaner. it really pulls out grime like you wouldn't believe but leaves a layer of protection behind. you may see it excel on white because of the grime that it pulls out of paint. if you use 601 then 501, within 2 hours you can top with 105. add 601 before 105 and it will be cured within 2 hours. do a final wipe with aqua wax and you won't believe the finish."
from richy: "I've had a few large vehicles to do lately and did not want to take the time to do both 601 and 105 so I spoke to Jerry at Duragloss and he suggested I combine the 2 in a 4 to 1 ratio of either 501 or 105 at 4 parts and 601 at one part. I bought a couple of cheap dollar store plastic ketchup dispensers and mixed 2 bottles up...one with 601/501 and one with 601/105. It worked like a champ. The only downside Jerry said is that the shelf life would be very short; measured in hours. I found that after 2 days it was maybe a bit thicker, but still working very well. This saves one step for each product (501 and 105) and saves time. In addition, you are still getting the benefit of the 601...flash cures, longer durability. I wanted to share this info as I know there are a lot of DG fans here on AGOL. Just mix up small batches and you'll be good to go. I used some more tonight and it was still fine after 4 days."
