Mike, (or group),
How would you recommend filling paint chips on a car that' already coated in cQuartz? Would it be the same process as without the coating? Do you reapply cQuartz to the area after?
I'll take a stab at this.
Is it just a few small chips, one here, one there sort of thing, or are you wishing to repair a considerable amount of road rash that has occurred to the front of the hood, front bumper?
If it was just a few chips at most, I myself might simply try hand polishing those specific areas with an ultra fine hand polish, then cleanse those chip areas with an IPA prep to insure polishing oils and polish residues were gone from the chip so that the touch up paint will bond-adhere better without future problems.
If it was more than this, such as the road rash scenario I mention, I'd more than likely be inclined to whip out the D/A Polisher, and re-polish entire panels.
In any case if you want the protection of CQuartz on that newly applied touch up, yes, one should re-coat.
For fast curing paints such as Dr Color Chip, I'd still probably wait a good week for paint to fully dry-cure before coating, or any possible further polishing processes are done.
For slower drying factory type touch up paints I might be inclined to wait even a longer period of time.
When I firstly went over my entire White Tahoe with Dr Color Chip Touch Up Paint wherever there were rock chips, I waited a full week before beginning any polishing, or with the CQuartz UK Coating I used.
