Using a bosch GEX150T

I suppose it depends on how intense your passes are.

I'm going to need to get to one of D's detailing days I suppose to get some further expert tuition.

Based on my experience on my first (and only!) detail, I would bump the speed up again as I can't really say I had issues controlling the Bosch but if there is a good reason why I shouldn't use a higher speed then I'd be more that happy to heed the advice.

I've also done my polishing at no higher than 2 on the GEX150T.

The heaviest swirls I have removed has been in two passes of 203S on FI Orange. Here's an idea of only two newb passes on my first detail:




Spread the polish on speed 1, then bump up to speed 2 and criss-cross in both directions over your section. I think I move at around 5cm per second (relatively slow) with only enough pressure to control the polisher (no real extra downwards effort). After you've done the section (horizontal back-n-forth, then vertical back-n-forth), the abrasives should have broken down.

There was a good video out there, I'll see if I can find it.

CAP Medium would remove those kinds of imperfections with a Single pass.

That info is a general technique, for the CAP Range I recommend using a slightly overlapping Grid pattern, speed of ~1.5 on the GEX150T, ~2.5-3 on the ROtex150 and ~4.5 on the ROtex125.

By overlapping grid I mean this:

There is no need to use the Cross Hatch method with efficient polish, pad & machine combinations and the machines like the GEX150T, ROtex150 & ROtex125, CAP Medium or 203S and quality pads are very efficient systems imo.

imo, Cross Hatching can agitate overcut abrasives onto already perfectly corrected areas. When you move the blunt/used abrasives back onto the section you completed at the beginning, you are burnishing spent abrasives and that reduce gloss and adds marring.

The Grid pattern (provided you primed the area*)

*by priming I mean moving the pad & polish around the area to be corrected on a low speed prior to carrying out the Grid pattern correction at full speed so as you move the machine down through the pattern it collects yet to be refined abrasives continuously, so the distribution of abrasives onto the moving pad are consistent throughout the movement from top left to bottom right.
Each section you pass over will correct, refine & burnish (with efficient polishes) in one movement and don't require agitation once you have passed over.

By the end of the movement down to the bottom right corner, all abrasives applied to the area are spent. If another pass is necessary, the corrected area should be cleansed to remove all abrasive particles and new polish applied.
