Have you used it? Is it true to its advertisement?
I always thought wheel sealants were a gimmick, does it really work?
Some of these bottles can be expensive. I'm sure many people have purchased an expensive cleaning product only to be thoroughly disappointed with the results and end up chucking the bottle in the trash can after its first use. It's happened to me several times. I don't mind paying the money as long as it does the job.
