Yes, I plan on using them together, but I couldn't decide which two products to use. I guess I should have phrased it a little better. Basically, I have narrowed down the polish to either CG black light or BF gloss enhancing polish and narrowed down the detailer spray to CG V7 or BF polymer spray. I was trying to figure out which was the best. Some brands are better at some products and not as well at others which is why I asked the question. I wasn't sure if in this particular situation, if both products made by CG was the better choice or if BF was OR if maybe one company for the polish and the other for the spray. I hope this clears it up. Thank you again.
