Thanks for not understanding my point, let me lay it out in simpler terms...
Why would I want to spend one cent more then I already have? You are right, $13 here, $20 there IS peanuts, but when you add sum of all parts, detail supplies add up quick. A fool and his money shall soon part.
My old 4' paint brush (that I HAD) works great. The brush applies clean and even and also get inside the ridge between the rim and tire. The block sponge applicator just does NOT, you have to press down to get in there.
Along with the country crock bucket with lid (that I HAD) there's almost NO wasted product. I pour about a quarter bottle in the bucket at a time my 32oz bottle is going on 8 months.
Now let's recap:
IMO the brush owns the block sponge applicator hands down on tires. Plus my fingers don't get dirty. Plus I don't need gloves or wasted time needed to put on said gloves. Plus it doesn't cost me ANYTHING.
If that's your method great, I'm not knocking you. Ive tried both and gave MY opinion. Maybe you should try a paint brush
