I thought I read that BFCS works with anything once it cures, thus meaning you could top it with a nuba? OP you have some great products there, BFCS is a miracle in a bottle, flashes clear in 45 minutes and leaves the paint poppin'! One spritz per panel is more than enough, just make sure you give the applicator a pre-squirt of the BFCS first. Speaking of the BFCS, I prefer using a square cotton applicator myself.
The Collinite #845 is a recent product for me but it really produces the results and is supposed to be good for 6 monthes but for me that's not a big deal as I'm an self admitted "product waster", LOL! The BFCS is so easy to use you'll find yourself using it quite often, its easier than using a QD even!
Let us know how you liked using the products, please include pics too.
