Yep i used a lot. Almost to the point i think i used too much. I was very conscious to get every area. So I think I'm good.
I'm by far no CQuartz Expert, and haven't yet even gone through my first 50ml bottle of UK. But I think if you have noted a good application with no high spots, smudges, streaks, or any other oddities, I would say you're good to go.
I've seen such with some other coatings, (DP) some very slight evidence on my Kia's Hood of what looked like thickish mis-application which once after dried were only going to probably come off by polishing. Didn't really care about this daily driver so much about showroom appearances, considering the hood is also quite loaded with rock chips, and other nasty damage.
Without a doubt, time taken, good lighting, do surely help.
But, I have a whole fresh 50ml bottle of UK sitting in it's lovely box, a Tahoe that's now basically coated except for inner door jambs, tailgate, under hood paint, which will use probably not even a 1/3rd of this unopened bottle.
I know once I open it, the clock starts ticking, and I'm scratching my head this end of what else can I coat?
Well, I have two pristine Racing Bikes, a Bianchi and a NOS flawless Schwinn 50th Anniversary Paramount in Pearl White Metallic with 24ct Gold Plated Fork, 2 killer Refractor Telescopes at about $12k for the pair, even crossed my mind to Coat my 1980 Slingerland Barret Deems Drumset in White Marine Pearl Wrap?
As for the Deems Drumset, I think no, don't do anything dumb, the wrap is not Paint. I value this pristine drumset that Barret actually owned at about $7K. Maybe Reload would be a better choice!
As for coating someone else's vehicle here, not happening. People here will just not pay what my work, and products used are worth, I'd rather flush the UK down the toilet first.
