Excellent results, easy to use, impressed!
Size: 8 Oz, Size: 8 Oz
I used the glide coat ceramic sponge applicators (it’s what I had) and the absorption was perfect. Application on trim pieces was super easy. Had to get a little particular around my mirrors and window trim (I didn’t tape, oops) I used 4-5 throwaway microfiber towels to wipe excess. Super pleased with 1st coat, may go back for seconds on my tonneau. I left each section to cure for about 7 minutes then wiped with towel. Leaves a nice matte finish that pulls out the sparkles in my Raptor trim. No sticky residue leftover.

Very good but over priced!
Size: 8 Oz, Size: 8 Oz
Great product and works very well. I was disappointed because of the high price and the small size bottle. But other than that it’s a very good product and makes my work van look clean, shiny clean. My van is white, but it was easy to clean it if I missed up. Good but over priced!

Super good
Size: 4 oz Kit, Size: 4 oz Kit
Super easy to use and seems to dry quickly. I think it’s a great value for the price. I can’t say how long the results last for but the process is easy enough and the results are good enough that I’d be down for doing it every couple months. It dries black and made my trim look brand new. Honestly the hardest part was just taping around the side mirrors. You should definitely get this if you’re on the fence about it.

Superior trim restore product!!
Size: 8 Oz, Size: 8 Oz
Superior product!!! Best plastic and trim restore product I've ever used. I have a 2002 Camaro kept outside in the FL sun and this did an incredible job turning back the clock! Worked on the t-top rubber, front grill, and also in interior plastic panels that had gone grey with UV exposure. People can't belive my car is 24 year old and not garage kept thanks to products like this...
