Collinite Sapphire PreWax Cleaner #840 issue?

[kavncool]

Anyone has experience for this product? last week i used it before applying 845, and i

found that it is really hard to buff off by hand..."just wondering why"

I use 7424XP and CCS black pad with speed 2, and buff off by microfiber towl by hard

Haven't used this myself (see below) but on the AG product page they mention that #840 will need to be buffed off almost immediately & seem to suggest it may be best used by hand. If using a machine they suggest working no more than one panel at a time before buffing...

Did you do this or work on the whole car then buff?

#840 is also recommended only for single-stage paints, not base/clear.
Others may have used this on clear-coated cars & had good results (I'm not sure...) but I have stayed away due to that recommendation...

-I realize that there are tinted clear-coat paints...

-But because of what the Collinite folks actually mean in their #840 product description
is unclear (pardon the pun) to me, I do not use it on any BC/CC paint system.

-Light-colored clear-coat paint vs. Dark clear-coat paint?
Just means, to me, that any "marring" incurred from #840's usage is harder
to see on/in a clear-coat top-coat paint film that's atop
a lighter colored base-coat paint that's integral to a BC/CC paint system.

-I also recommend reading #840's application/removal processes.


2. Recommended for:
• Tarnished/soiled/stained/discolored/weathered surfaces
• Light colored clear coat paints (?)<<<My questioning mark (white, silver), fiberglass, gel-coat

2a. NOT for use on:
• Dark clear coat paint (?)<<<My questioning mark or painted metals
• Surfaces unmentioned above, as testing has yet to be extensively conducted. Refer to Collinite
directly with application inquiries.

Hey Bob, what I think it means is that for light colored cars that have a clear coat, it's good. And for dark colored cars that have a clear coat, it shouldn't be used.

Thanks for your reply ihaveacamaro.

Yes...I do understand that's what the 'Collinite-Folks' say...

But...Why is this so?

As I alluded to earlier:
Is it because it's harder to see swirls/marring in a clear-coat that's part
of a lighter-colored base-coat: BC/CC paint system...
...No matter the brand name of the pre-wax cleaner,
or other abrasive-containing products, that's being used??...Or not?!?!

Any answers/input that you offer/provide regarding this issue will be appreciated.
Thanks!

First i work half panel then buff off, but it seems really hard to buff off, maybe last time i

will try to use hand to see what happen....
