Manufacturer claims:
BLACKFIRE Wet Diamond Polymer Spray creates a long lasting shine with a high concentration of BLACKFIRE’s amazing tri-polymer Wet Diamond polymers. This spray-on paint sealant contains light cleaners to remove dust and smudges while reinforcing and extending existing paint protection. Use it over waxes or paint sealants to maintain a fresh, clean shine all the time! Each bottle of BLACKFIRE Wet Diamond Polymer Spray is packed with Wet Diamond polymers making this an excellent stand-alone sealant as well!
Blackfire Polymer Spray is one of my favorite post wash boosters. It really plays well over every LSP I have tried it over, but where it truly shines is when it’s applied to any Blackfire LSP. My car is currently wearing BWFD with layer of Crystal Seal. It’s very well protected but it hasn’t been topped up in a while. Perfect reason and opportunity to rip out Poly Spray.
Application is simple, simply spray a mist or two on the panel, and with your towel of choice(I opt for Gold Plush Jr) just gently massage the product into the paint and it will literally disappear. No buffing, no extra wipes, just spray wipe and watch it melt into the paint. It really adds tremendous gloss to the paint, and brings back the Blackfire look we all love so much to life!

Creates an extremely slick surface for a spray wax/ spray polymer
Can be used as a QD, albeit I’ve never tried that.
Will extend the life of your LSP of choice. I have seen this in particular when used with other Blackfire LSP’s. It brings life back to the sealant, it creates such a slick surface it will aid in your next wash making dirt a little bit easier to get off. It works well on windows too, since it dries streak free, I’ve never noticed it cause any issues on my windows. I have DP Glass Coating on my windshield, and Poly Spray provides a little boost there as well, even though I did not need it, I do it anyway lol.
Can be used as a drying aid, or on a dry clean surface. I have had success with both methods, but I tend to always completely dry the car first then apply.
Price per application is great. I’ve had this bottle a year, and used it maybe 12-15 times and most of the bottle is still left. I’d say I easily have another 30 application, you use so little, its great!
Cons:
I don’t like the sprayer all too much, I transferred it to another bottle with a myst sprayer I like. This is not really a knock though, I do this with pretty much every product. I hate supplied bottles lol, the product is great, the bottle and sprayer, ehhhh.
