***4 Day Update***
The tires were driven in the rain and approximately 100 miles on day 3, so about 150 miles total since the initial application.
Keep in mind that only one coat was used for each tire dressing.
All of the dressings are about spent and there's just a light sheen left on each, a couple have a little more sheen than others. All of the dressings exhibited a little bit of streaking but the Duragloss 253 exhibited the most. You could say these dressings were put to test.
The sky was overcast when these pictures were taken.
Megs Endurance Tire Gel - I thought there would be more shine on this one since it is solvent based.
Carpro PERL
Chemical Guys VRP
Duragloss 253 - This one was almost completely gone and exhibited the most streaking.
Final Thoughts
All of the tire dressings I tested in
Face Off 1 & 2 appeared to be good quality dressings. I don't think you can go wrong with any of those dressings. Some lasted a little longer than others and some had a little more shine or sheen than others but not by a whole lot. I think it really comes down to personal preference. Also, you may get different results on different brands or style of tires. Best thing to do with water-based dressings is simply reapply them every time or every other time you wash your car.
A Word About Tire Coatings
If you don't want to deal with dressings your tires often then tire coatings is the way to go. I have noticed that applying a tire coating on a tire with more grooves takes a little more time and effort to make sure the coating is spread out evenly or else you will have some spots shinier than others. Also, if a tire coating is applied incorrectly it will take more effort to remove it completely than a water-based dressing.
Here's a tire coating (McKee's) applied to my trailer tires back in January 2018.
And here's what they look like today (May 26, 2018), about the same as the day it was applied. No dressings have been applied since the initial application. These tires have been driven many miles and some of those miles in the rain.
