long lasting tire shine should be the last of your problems ... anything that seals a tire is not only voiding the warranty but will lead to premature dry rot and possible blow outs ...
this is not from me (remember I sell tire dressing) but from the tire companies ... go to the source , the tire company that is on your vehicle ...
When I use a dressing , it has to be water based and I usually will wash it off after a few days and keep the tires clean.
As stated previously the blooming or brown dirt that come out if you scrub and scrub is part of the compound that belongs in the tire ...
Clean the outside of the tire, dress it if you are a professional or going to a show .. but long lasting is not the answer ..
Hmmm. I hate to disagree with your expertise - and in THEORY you prolly are 100% correct. However, in reality, I`ve been using TS on my DD tires almost since the day it came out and have not had a single issue. This is multiple vehicles & 3 sets of different tires.
It really is a beautiful product. One of the few "set it and forget it" products out there that really is worth a crap.
The beauty of it is:
1. You can clean the tires with regular soap. They never seem to get dirtier than paint.
2. When you want to renew it you simply clean the tires with soap and apply another coat. You do not need to scrub the tire naked ever again.
3. It really does look great for a very long time.
4. It virtually eliminates any type of tire detailing other than slapping another coat on every few months.
5. No more greasy silicone filled nasty black tire dressing applicators.
6. Zero possibility of sling.
7. No worry of "dressing grease spots" in yr driveway (well, mebbe a benefit for amateurs using spray silicone heavy dressings)
8. It`s pretty cheap in the scheme of things. I bought the $50 16oz bottle years ago and it`s half full still.
