Reviving this old thread. I finally tried Turtle Wax Flex Wax for the first time. I know its been a while since my original post, but it took me that long to get through a gallon bottle of Xtreme Solutions Topper before I was ready to order a new drying aid / spray wax.
The Turtle Wax Flex Wax provides a very high level of gloss. The graphene in this product really does add additional gloss. So if gloss alone is your main goal, I would definitely recommend checking out this product. However, I also consider other factors like slickness and scent. Does it glide under the towel as you wipe it off? Does it come off easily without streaks or high spots? Does it have a pleasant scent?
The TW Flex Wax was a bit slick under the towel, but not nearly as slick as other products. It is also a bit more work to buff off. As others have mentioned, if you use too much, you will likely have some streaks. Finally, it doesn't really have a scent. So I am glad it does not have a harsh chemical smell, but it also does not have a pleasant scent.
The final factor for me is cost. TW Flex Wax costs about $25 for 23 ounces. My other two favorite ceramic drying aid / toppers Technicians Choice Ceramic Detail Spray and Xtreme Solutions Topper are more cost effective at $35 - $40 per gallon. Plus, they both smell great and are pleasant to work with.
So although I am glad I gave TW Flex Wax a try, I am going to stick with Technicians Choicer Ceramic Detail Spray and Xtreme Solutions Topper.
Then again, I would like to try Griot's Garage Ceramic Speed Shine and Meguiars M799 Pro Ceramic Bead Booster.....
