I find that I can notice pigtails with 1500. I like to finish with the foam pads. I have used:
-Eagle Yellow Film (dry)
-Sunmight Green Film (dry)
-Klingspor PS11 (wet silicon carbide)
-3M Purple Trizact
My ranking of them is a toss up between the Eagle and the Sunmight. I don't care for the purple trizact 1500. I do like the Trizact with the foam backing pad at 3000 grit. I've found a better option to trizact are any of the other foam pads Sia Air, Fandeli Supreme Foam, or the other big foam manufacturer (names slipping my mind) starts with an M and they make a line of dry paper called Bulldog.
What I've found is it's very obvious that you used a DA and missed a pigtail scratch or two. It's not as obvious with an inline sander. Because of this I've switched to using a National Detroit Model 600 inline 1/3 sheet sander. It's just as fast as my Dynabrade was and if I somehow miss a scratch or two in buffing it's no where near as obvious as the Palm sander (dynabrade). A little more information on my palm, it's a Dynabrade Silver Supreme 3/32" orbit (the fine finishing orbit).
I am now using Full sheets of wet dry paper. I've used:
-Eagle Silicon Carbide Wet dry
-3M Imperial Wet Dry (the usual at jobber shops)
-Fandeli Wet dry
For the price the Fandeli does a good job. I have yet to be disappointed by any of the three above though.
All in all, I'm much less worried about my work with the inline wet sanding and it's just as fast. The paper is much cheaper to boot. No need to use foam pads (trizact etc) so I'm very happy. I hated it when I'd think I'd have it buffed just perfect and look real close and see a pigtail reflecting in the light. Now I don't have that to worry about. An inline scratch is MUCH less obvious than a pig tail. And when it comes down to it, every sander leaves a scratch. There's no such thing as using a DA and not getting pigtails. It's just not possible. That IS the scratch pattern of a DA.
