Just looked at your Rotary, 2-3 is way way too high. Starting speed is 1400 on yours.
Mine is 900 and estimate speed @ 1.5 is about 1500.
You must have been polishing at circa 2.5k+!!
No load speed of 1400. If this machine doesn't have a constant rpm circuit which i'll assume it doesn't then thats about the same as mine. 3-3.5 for correction is fine.
Anyway the hologramming is because you either used a harsh combo which won't finish down nicely or you didn't fully work the polish.
Tbh Farecla isn't a particularly good starting place for beginners. Even G10 can be tricky to finish down without hologramming. By comparison, Meguiars #205 is a pleasure to use, 105 is a great compound too I recommend trying them out. Autobrite are selling the 250ml bottles again now if you don't want to spend out on the huge bottles.
