nicest things

We starting working with Corey this past year. After bringing him several vintage Range Rovers he has become a key part our process. We wouldn't think of completing a car without sending it to Mountain Detail for the final detailing, paint correction or ceramic coating. Well worth the investment!

I’m very particular about my vehicles and who works on them. I recommend Cory because of his knowledge, professionalism and attention to detail. Mountain detailing will be taking care of all my vehicles from now on. Worth every penny.

I brought my motorcycle to Mountain Detail for full paint correction and ceramic coating. The bike came out perfectly. It went from having the typical streaks and swirls in the clear coat to being flawless. If you're looking to protect your machine and have it turn heads, I highly recommend Mountain Detail.

They ceramic coated my wife’s Cabrio and the results speak for themselves! No more waxing, shines like crazy and the water sheds off like nothing I’ve ever seen before.

We are not fancy car people, but wanted to revitalize our 7 year old SUV. We never had a "real" detailing before, but heard such great things about Mountain Detail, we gave it a try! Pricing was reasonable, service extraordinaire and customer service was outstanding. We'll be back. Corey is the BEST!

We received a ceramic coating package for our GMC 2500HD Denali. This is no regular auto detailing that your vehicle will receive. My GMC was done almost 4 months ago and it still receives compliments on how great it looks.
If you’re looking for the best, this is it!

Corey is totally amazing at what he does, the level of professionalism is second to none. Your vehicle is a big investment and he brought my paint back to better than factory finish and then takes the time to show you how to maintain finish!

My truck has never looked like it does, the pearl in my paint shines like I've never seen before. Corey's work speaks for itself. I would highly recommend him to anyone looking to preserve their vehicles appearance for years to come.

Corey is absolutely one of the most knowledgeable people in the industry when it comes to paint correction, and paint protection. If you do your homework you will quickly recognize that he is one of the chosen few that are talented enough, while keeping high enough morals, to be CARPRO certified!
