tried it, finally, today on a DA with finishing pad. my impressions so far are.. WOW! it goes so easy and a little is more! much more!
this is how much i've used on a BMW X5 except roof and bumpers (line is on top, where the bubbles are):
that's great!
i too was looking into PB Black Hole and Colli 845 as a combo but was afraid i will loose in durability!
but you have some positive experience. thanks for sharing!
been reading here to left cure for 12 hours before layering.
if my car stays outside (no garage, i'm afraid) - should the car be quick rinsed just before the second layer (in 12 hours)?
