How well does Collonite 845 layer?

I'm wondering if its layerable at all .. seems like it has a high solvent content per the MSDS .. wouldn't that remove the layer below. As far as super durable .. I wouldn't class it with FK1000 .. in side by sides 845 didn't do as well as some of the other sealants I have used.

Yea, I wasn't expecting near the 4-6 months of protection I get using fk1000p on my white car, from the 845. It just every time I apply the 1000p to my dark blue car, I get those pseudo holograms everywhere. The only way I don't get them is if I apply the product to a freshly polished surface with no glaze. I like my glazes.

I never really had any issues with 845 layering. Actually I prefer to do two coats, as the second coat lays some much more smoothly and is easier to buff off.

Heh heh....Hi Alfisti!
Yeah, I've used a lot of 845 and yeah it does layer for me. I always wait a day or so between applications but I have no idea whether that's really necessary and I suspect that it's *not* given the product's original application/purpose.
No issues with pseudo-holograms (that was with FK1000P under certain circumstances) or with QD-sensitivity (that was with 476S).
BUT...appearance diffs between 845 and 476S seem to fade/even out after a wash or three and 476S is far more durable for me (if less trim-friendly). And FK1000P is *FAR* more durable then either; I switched most of my drivers over from Collinite even when it looked better (to me) because the durability/protection of the FK is the best thing I've tried this side of a coating.
These days I really only use 845 as the base layer under 476S. I do this because the 845 *is* much more trim-friendly and it's a lighter product less likely to cause issues over a seriously imperfect paintjob (think pits/not-so-micro fissures/etc.) and I only use Collinite on paints in very poor condition. When I used Collinite on other vehicles, the 845 base layer helped with the issue of product build-up along PPF edges (and remember that I apply *VERY* thin layers...still sometimes had problems but the 845 helped a lot).
