I have been chasing the magic bullet for quite some time. I have a garage full of 3/4 full bottles of everything. Why? I like to try the newest things, am looking for a better weapon and the best looking car.
I can really tell you that if you prep the car properly the LSP is going to look awesome weather you use
P21S or Turtle wax.
Durability and ease of use aside. Your client, unless he is very decerning cannot tell either. I know some guys have better eyes (read experience) than me, but for 99% of the world it look drop dead awesome.
For the other 1%, I see those guy at a local shop paying $ 900.00 and up for a 3 step and LSP. Cars look sick but for me not worth the extra coin. If your lucky enough to have that market-hit them hard but deliver the perfectest product man can achieve. I have seen some write ups by some guy in Florida Bella Machina-he is wild. I do not know him but his write ups are PHD quality thesis papers. Its about more than his work, it the presentation and the sale of the perceived value. Again-not for everyone wallet.
Something different drives each customer. I loved the carnubas for a long time. Now I am looking for a optically correct reflection that only a sealant gives me. Thats my opinion and my mentor feels differently about his black 5 series BMW and we are both right.
In business you need to cater to your customers percieved value and specific needs. I think I would diferentiate based on services levels provided not on products provided. You can get great results with any one of many nubas from 10 bucks to 500 and same for sealants.
If you get a guy who talks the talk, use whatever he wants as long as you can make it work.
Good luck!
