Ruben,
I had the exact same issue with all collinite waxes; 476, 915, and to some extent 845. Not so much with 845 though. I also have a black car and had residual oils left on my paint after leaving it for about 5 minutes to dry. I tried using better quality towels, same problem. Tried to wipe off the oil, it just spread everywhere. This all happened despite all my efforts to get it thin.
I got around this issue by not leting it dry too much. This was my technique;
-used a foam applicator moistened with distilled water.
- I lightly rubbed the applicator over the paste twice with little pressure.
- worked in a 1x1 foot area.
-I let it semi dry for 5-10 SECONDS
-Wiped off with a 350 gsm microfibre towel
That was the end of those oily holograms. I can predict what people are going to say.. " wont that affect durability?!?" So far the answer to that question is no. I did a side by side comparison of 476 wiped off after 5 minutes of drying and 10 seconds of drying on the hood of my mums car. It has been about three months now and both the sides look like they are holding up very well. The side that was left to dry 5 minutes still has the oily swirls.. washing did not get rid of them.
I cannot comment on the effectiveness of this technique to prevent sweating.. it isnt summer here in australia so there is a very low chance of it happening anyway. Summer is a different story!!

Ill have to test that out.
Try it out and it should work. The key is to not let it dry completely!
