A: Use a wrench or socket sized for 5/16 in. hex bolt heads; check your tool set for the matching SAE size.

It really does the job!
Size: 8 Oz
This stuff actually works really well. It brought all my plastic back to life. And although I don't think it's designed to use on metal my toolbox is black and it looked faded and I did the toolbox with it and it looks brand new now. There's a die in this product that makes it last longer than most other products I believe. And if your plastics are really bad like some of mine were give it to treatments and you'll be amazed. You have to let it dry for a while it will be sticky depending on the climate for a day or so but it's pretty much dry it won't you know smudge or anything but it just feels sticky to the touch for a day or two. I've been through the car wash a few times since I treated it and it didn't hurt that new finished. I do recommend this product.

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.
