Optibond is currently my go-to tire dressing. I picked up some of this from a member trade and i have been very pleased with it. i also have the carrand tire dressing brushes that you ordered.
here's my $.0.02 on each of these:
I have used optibond straight and 1:1 out of a spray bottle and for me it works best straight up. I have applied this with both the tire dressing brush you purchased and a foam applicator pad picked up at local auto store.
Looks: One coat of optibond, unless applied quite liberally, seems to yield a nice matte, or very slight gloss look. I have tried two coats and it looks glossier but I prefer the gloss high gloss look of other products over two coats of OB.
*from my experience with ob, it looks much better on tires that have smooth sidewalls instead of once with lots of little ridges on them-hopefully that makes sense to everyone.
I love the look it gives the michelins on my frontier (which have mostly a smooth sidewall)
When using it on tires with ridges that carrand brush will come in handy because of all the bristles but the watery consistency of OB does not seem to work for me as well with this brush as something like pinnacle black onxy gel (which is my personal favorite)
I have had overall better results applying OB with the cheap little yellow/black foam tire applicator pads you get in a two pack from walmart or autozone.
Dont get me wrong the carrand brushes are pretty good I just like to use a thicker tire gel with them. If you dont apply too much OB on the brush you shoudn't have a problem and the brush definitely does help to get inside the little ridges on most tires.
I have only seen one incidence when OB actually slung onto a vehicle I had used it on. The tires were bfg all terrain tires (that are completely unnecessary for where we live here in central tx) and even after sitting on the tires in midday light for over 30 minutes it slung a few tiny little dots but I am going to chalk that one up to user error on applicatoin by myself. I tried to get too much coverage.
OB works pretty good on fender wells, I have directly applied it to a couple with a foam paint brush, I tried to spray it 1:1 but liked the control of the foam brush more.
Durability: I have personally seen over two weeks of nice matte look on my frontier's tires and it sits outside 24/7. I can even wash my truck a couple times (ONR) and if i dont use apc on the tires OB sheds the water right off and looks almost as good as day1.
Would I purchase this stuff again, Yes. But i think I have enough to last quite a while (still well over 1/2 gal). I transfered it to the 2 oz travel bottles with pump on them and one 2oz bottle will put one good coat on I'd say at least 10-15 vehicles depending on tire size, probably more acually. I put three little dimes per tire on normal size tires and that works fine with the foam tire applicator i use. I found myself using more OB with the carrand brush.
sorry for the exhaustive response but it's new years and I have the day off and football has not started yet
