You probably seen my videos on rustproofing over the years, I've sprayed almost every product known to man. The question is, does that "permanent" tar rust proofing stuff really work long-term?

The answer is a little bit more technical. The permanency of this product was based on the fact that customers would return every year for touch-ups. If customers don't return their warranty is null and void. Now did the dealers and the people who applied this product, including myself, expect customers to come every year forever? Did we process any warranty claims? What is the life of a vehicle?

These are all further questions we can explore some other time.
