If a product could add 5 years of life to your roof.Would you?

If a product could rejuvenate comp. roofing @ 20% cost of new would you be a customer?

There is a soy bean oil product that can be sprayed on composition shingles and it makes them plyable again. Like from bend and crack to bend and flex back. It even brings the original color back. I have seen it. The question isn't does it work. The question is would it be worth it to get five additional years for 20% the cost of new. It can be reapplied every five years a total of three times. So is 60% cost of new worth 15 years? Seems steep to me. What do you think?
