Runny consistency, apply very very thin
I replaced the cap with flip top cap so that I can put just a few drops at a time on the pad. I apply with red pad on PC
edit: Using a 4" pad. On first panel I use 5-6 drops, 4 on second panel, 3 drops per panel after that
Variation on that theme, I start by dripping a half dozen miniscule drops on each side of the hood. Once I spread it I rarely have to add more than a drop or two to the pad for additional panels, whether applying by machine or by hand. Once the pad is saturated the stuff seems to stay there forever.
Interestingly, I pinged Collinite with my thoughts on the cap when I forwarded them my shipping address for something I'd won. They replied there were some good reasons they use the cap they do. Then they threw a couple of flip tops in the box with my goodies. :dblthumb2:
Another tip.... when I get down towards the bottom of a bottle (which takes years and years!) and 845 is super-thin and runny I pour the remainder in a 4 oz bottle with a spray atomizer. It took some experimentation until I found a mister that didn't clog. I use these to lightly mist when my finish is still in good shape and use it like a WOWO spray wax monthly to maintain the remarkable Collinite beading and shine. As a result, as long as I don't need any additional correction or cleansing, I usually only have to clean/polish/wax before winter every year.
For the OP, as others stated, it takes a bit of perseverence to reach a runny consistency by shaking or using the hot water method. Every time you open the cap push the plug back down in the bottle and shake some more. Lather, rinse, repeat. Once a 1/4 of the bottle is used it gets easier once you've made some shake-room in the bottle.
If you don't have any trouble seeing 845 when it's going on... especially on lighter colors... you're using too much. Another tip, sometimes 845 comes off a bit smeary. Let it sit for a while and use a plush MF to vigorously but lightly buff off any smears or residue. I final wipe with a QD or even a light mist of water for the final touch.
