When to use paper on blocks vs paper on a DA?

I'm restoring a 65 Mustang, going for a concourse look. Painted the old hood base clear and it looked modern to me. So I got some single stage. Came out with too much peel for my taste. I'd like to see what it looks like cut and buffed. I have a bunch of durablocks. Do I need to buy rolls of sticky backed paper from in 800, 1000, 1500 and? Are durablocks a good choice? I have a good selection of fine grit sheets, super newbie question, but what do I put those on if I want to use them, and what holds them?

At what grit do you switch to a DA with Trizac? at 3000? Is that decision based on grit, or?

Is lack of peel in my BC/CC what made it look modern to me, and if I take most or all the peel out of the single stage will I think that looks too modern? I still have almost the full gallon of Universal clear left if I decide to use it :)

Here is a picture, probably can't see the peel on a monitor. This is the old roof, so I didn't do any bodywork do it besides using SPI epoxy on it.

What single stage did you use and how many coats did you apply? If I'm going to block and buff a singlestage I shoot for a minimum of two coats past full coverage and my normal routine is to shoot three coats, sand, and apply 2-3 more before the cut and buff. It does have a different look compared to bc/cc. I use plexiglass blocks and sticks for the majority of the sanding and progress from 800 or 1000 to 1500-2000 then switch to a DA with 3000 then 5000. How much wave or peel determines what grit I start with.
 
For a true original look on a 65 ford I think you'd have to shoot it with enamel and leave a little texture in it, these old cars didn't have the perfected wet look I think.
 
Thanks Bob, that's 4 wet coats of Valspar 840 from the local guy who can't figure out why I buy everything but paint from him.

What grit do you use between the three coats and the 2-3 coats?

I hear you about the enamel, not sure if I'm willing to go that authentic, lol

I go with 600 wet. I'll bet Bob probably does the same. You can't go wrong if you wet sand it with 600 on a block. Some go as coarse as 400 but I've always had good result with 600 wet.
 
I use a variety of blocks and sticks, different lengths and widths. Most of them are made from 1/4" thick plexiglass, some wood, some rubber and foam for contour sanding. Some people use balsa wood

They have to be hard, right? No foam sanding pads? What about convex areas?
