Option 03: As long temps are above freezing point I suggest you use warm water in your bucket with ONR. Spray opti-clean as your pre-wash and wash it straight with ONR. Youll be suprised how slick & effective the wash will be. Dry with opti-seal or OID.
Welcome to the forum
Id love to hear more from you about how you run your mobile business, the products you use and so on...
OPT Gloss coat is a great product...not only incredibly easy to use but it performs great and lasts quitw a while.
Its not ideal...Opti-clean will evaporate quickly on a hot panel. Its always best to wash the car in a shaded area and when the car is cool. If you cant find shade then wash your car early in the morning right after sunrise of late at the afternoon just before sunset.
Both are soft so I wouldnt be so concerned...Also GPS isnt a compound. It will finish nicely.
I say do a small test spot. Use the softer black one first and if you get the results you are after go with that. It will certanly increase gloss.
If you want more cut (remove more swirls) use the white pad.
