I noticed bubbles in my window tint on the drivers side! You guys were very nice and helpful explaining the bubbles will evaporate and if they do not it is 100% guaranteed! I highly recommend this shop.

I did undercoating and rust proof.
From the get go, Sam was friendly, honest, patient, and understanding, so after shopping around I decided to go with Sam.
He suggested that I bring in my car to his shop so that he could check the condition of my car and give me the accurate quote.
After going over the entire car, he offered me a lower price because he was being honest to tell me that there were factory applied shields and he wouldn’t have to work on many sections.
After they were done applying coating, he took me to the working station again and showed me the final product with detailed explanations.
I appreciate Sam and his team for working on my car, and for their outstanding customer service.

Excellent work!
2nd time I have been there.
I have to admit my 2nd time I was a little demanding and caused them some inconvenience. That said, they were very professional and went above and beyond in order to help me out even to the point of it costing them some extra money in order to make sure I was happy.
I will be using them for my next upgrade.
Thanks Sam!
