Well, I Gloss-Coated 4 wheels and I have mixed feelings about the process and results, mostly due to my being an Opti-Virgin. First, I purchased the smaller of the two sizes of syringes and I used close to half of it! I probably wasted much during the process, but I'm not really sure where or how.
First of all, I did a variation of Anthony's paper towel applicator method. I found what they call a sponge cloth which is a 1/8" thick sponge that I cut into small 2"x3" sections to more easily manipulate inside the wheel surfaces. (I hope this was ok.) I applied several drops into the sponge, wiped on the wheel for a while, then repeated several times for the face of the wheel and the barrels. I used way more than I thought I would. I was hampered by not being to easily see the Gloss-Coat on the surface and I didn't want to miss any area. I could generally tell that I covered the surface initially because of the wet look and then I could sort of see where it was heavier because of a pattern of my wiping motion was left on the surface. I did the whole surface of the wheel like this, being sure it all got "wet". I probably wasted a lot doing this. Then after a minute or so I very lightly ran a microfiber over the surface to spread it around. I really wasn't sure if I was spreading it around, making it even. Or was I actually wiping it off? I really wasn't confident that I was waiting long enough before I spread with the microfiber. Could I have removed it too early? I tried to do this as lightly as possible. I never really felt it get "sticky" as mentioned in many videos. But it was hard to get a feel because of all the tight areas. I repeated the light wiping until it felt essentially dry. I am not sure if it was really "dry" because I was wearing gloves and didn't want to touch it with my bare fingers. But the towel glided over it easily and I saw no more high spots or lines from my application.
The wheels are full of so many angles and surfaces that it was really hard to get an even coating. Would it be safe to assume that you would waste more on wheel application because of this? How can I more efficiently use the Gloss-Coat? I have half a syringe left and two more sets of wheels to do with more complicated and detailed surfaces. I can't see how I can get it done. Yikes. $$
I replaced the black tip in the syringe and reduced the amount of air in the syringe as much as possible. I cleaned the needle tip and set it aside. Is the microfiber I used to wipe and spread the Gloss-Coat essentially dead? Can it be cleaned or should I toss it? The small sponge cloths I used as applicators will be thrown away.
So how will I be able to tell if my efforts were worth it? Any tests I can do? I mean they look fantastic, but they did before I started, too.
