I had my tints done by the owner, Grant, and I couldn’t be happier with the experience. He’s not only a true professional, but also incredibly knowledgeable and clearly passionate about his craft. If you’re looking for any auto care services, you can feel confident and comfortable trusting Grant with your vehicle.

My experience with Sinfully Slick was absolutely fantastic from start to finish! I recently had both a ceramic coating and tint completed on my car, and the results are truly amazing. My car looks absolutely stunning, with a depth and shine I didn't think was possible. What truly set Sinfully Slick apart was the exceptional customer service. From the initial consultation, to the completion of the work. He made sure I understood the benefits and what to expect, which I greatly appreciated. It was genuinely easy to work with him – he was accommodating, professional, and clearly passionate about his craft. Throughout the entire job, he kept me consistently appraised of his progress. This level of communication was a huge plus, as I always knew what was happening with my car. The dedication and meticulousness really showed in the final product. If you're looking for top-notch ceramic coating and tint services, coupled with outstanding customer service, I highly recommend Sinfully Slick. You won't be disappointed!

I did a ceramic coating and tint on my Audi S5 and Grant did an amazing job! From start to finish everything was perfect. From the communication and education of my various options at the beginning to making sure I was 100% satisfied with the outcome. I really couldn’t be more pleased with my experience. I’ll recommend Grant to any of my friends and family and anyone who truly cares about their car.

Great communications and quality work done. It’s been more than a month and the ceramic coating and PPF on my new truck still looks like new and cleanup is a breeze. The window tinting was perfect.

This was my first time meeting Grant and bringing my car there to be detailed and I am very impressed with meeting Grant which by the way he has a great calm nature to him, very smart on his field and answered all my questions. I mean he works with his hands... I got my Rave detailed and polished and I am very impressed with his work, detailing, taking his time; I just hang out there waiting. My experience with him was superb and I will definitely will bring my car to him again.. From the start to the end Grant was great, he is sooo well educated on this field, my goodness " I ve been living under rocks" lol.I must say from looking up his website, to booking app, to answering questions via text he was soo cordial, intelligent, amiable and took care of all my questions and concerns. I thank you for all you did.. as I said; " I am impressed with Grant" definitely Highly recommend him and if you want to have the "high end of car detailing", please call him up as he is up to date on this stuff I will definitely will go see him again. Thank you Grant!! My car is " slick bling".

Grant did an amazing job tinting my 2021 corvette c8. The windshield tint that was initially placed was defective, and he replaced it free of charge! He worked around my schedule to get me a time most convenient for me as well. He is the consummate professional, and takes pride in perfecting his work. Highly recommend!!!

Simply put: “Exceptional!” Top notch customer service. Grant made a beautiful performance vehicle look even more beautiful. The carbon flash accents to my C8 absolutely pop. I put a lot of faith into Grant’s ability. He has exceeded every expectation. He has earned my trust!

I recently brought my 2025 Chevrolet Blazer RS to Grant at Sinfully Slick Auto Spa, and I couldn’t be happier with the results. Grant performed a full ceramic coating that completely restored the gloss and shine of my SUV. The process was thorough and professional from start to finish — including a snow foam and hand cleanse, clay bar exfoliation, bug and tar removal, rim and tire cleaning, paint correction, wheel sealant, glass cleaning, and even an undercarriage pressure wash. Every detail was taken care of, right down to the door jams, plastics, and wheel arches. In addition, Grant tinted my driver’s and passenger side windows with STEK ACTIONseries Nano Carbon Film, which not only looks sharp but also provides excellent heat rejection and UV protection. The tint comes with a lifetime warranty against fading and peeling, which gave me even more peace of mind. Grant’s attention to detail, professionalism, and pride in his work truly stand out. My Blazer looks better than brand new, and I’ll absolutely be returning for future services. I highly recommend Sinfully Slick Auto Spa to anyone who wants to keep their vehicle looking its best.

I brought my car here in a panic because my new used car had tinted windows that were too dark and my car wouldn't pass inspection. I needed to have the tint taken off. Grant took me in immediately, the next morning to have this done. I was nervous about what this would entail and Grant answered all of my questions and made me feel comfortable with the whole process. I highly recommend - Grant is a class act!

I can't say enough about the service and quality of work that Grant provides. Back in April 2025 I brought my 2024 Durango 392 in to have the factory vinyl racing stripes removed, and replaced with partial PPF, including carbon fiber look PPF on the hood, ceramic coating and tint. He also took the time to add some small touches that really made it pop, like tinting the headlights and adding yellow vinyl to the SRT logo to match the calipers. We did have one issue with the PPF on the hood not settling properly. Grant replaced it promptly for free and it looks great to this day. Fast forward to today, I brought my car in to his new shop in West Boylston because there was tar all over the drivers side. Grant did a full detail, the tar is gone and it looks fantastic again. I highly recommend Grant, not just because of the service and quality of work, but he is a stand up guy and really cares.
