My diesel is 20 years old but has been babies with only 64k miles on it. It was time to bring this truck back to life and that’s EXACTLY what Nathan did!! My 20 year old paint feels better to the touch than a brand new truck! And my wheels… I wrote them off as trash…, I didn’t think they had any life left! Needless to say I won’t be spending money on new wheels. I believe photos of my grey f350 are posted and the chrome wheels. I’m speechless on what Nathan did to my truck! 10/10 recommend with fast turnaround!

Nathan did a outstanding job tinting my Maserati windows. He is very meticulous and a real gentleman. I would unequivocally recommend him to do work for me on any car I own. Maybe. I’ll be bringing in my G Wagon soon.

Nathan did excellent work on my Subi. While my asks were fairly quick and painless, his professionalism and flexibility made Red Line a top resource and recommendation for me going forward!

Redline Concepts is the real deal. Nathan was respectful and very committed to providing the best ceramic coating service that the industry has to offer. His pricing is fair and the results were stunning! I highly recommend Redline Concepts if you want to protect your automobile's paint or bring back that showroom luster! Amazing results!

Redline Concepts didn’t disappoint! Nathan put Geoshield window tints on my kia niro and took it to a stealthy Ninja appearance! Having a black car with black leather seats had me melting inside. Now with the tints, I can drive in comfort and enjoy my car that much more. The quality of the tints is amazing and Nathan was professional, reasonable and fast. Highly recommend!! 10/10

Nathan provided outstanding service with careful craftsmanship and attention to detail, ensuring my Storeyteller Overland Van appeared flawless after paint correction and ceramic coating. His transparent and competitive pricing makes him a highly recommended choice for vehicle care.

I took my son’s 2005 Volkswagen GTI to Nathan at Redline to have some paint correction work done and the interior detailed. Now, my son’s car was looking and feeling like your typical teenager’s car. The paint was faded, especially on the roof, where it was so dull and had that milky white “sweat stain” look to it. The rest of the car was slightly better, but still not great. In speaking with Nathan about the condition of the paint, we decided to also do a ceramic coating to keep the paint work he would be doing looking great for a long time. The interior of the car was a mess too. Spilled soda stains on the console, grease stained seats and dirty carpets. I dropped off the car at 8am this morning and when I went to pick it up at 6pm this evening, I was utterly blown away by the transformation. The body and paint look absolutely amazing and the roof was reflecting the sunset like a mirror. The interior is spotless and you’d never know a teenager owned the car. My son is going to be thrilled with the result and I can’t wait for him to see it. Thank you Nathan and Redline Concepts for breathing new life into my son’s car.

Nathan did Excellent work on my 6th Gen Camaro. He is one of the few out there that has the attention to detail you'd expect for a car enthusiast. I had paint correction, ppf, ceramic coating and tint done. Highly recommend!

I have used Redline Concepts on four occasions on different vehicles over the years. Nathan has always been super to work with and the products have performed well — e.g., I still get positive comments on a Subaru Outback that has gone over 100K miles on its original ceramic treatment!

We took our 2015 GMC Denali truck to Nathan because the headlights had become extremely yellow and dull. He did an incredible job restoring them. They look absolutely amazing now! The difference is night and day and its made a huge improvement in both the look and safety of our truck. Nathan was professional, efficient and clearly takes pride in his work. Highly recommend him if you need headlight restoration or detailing!

I can’t say enough good things about Nathan at Redline Concepts LLC! 🙌 To save a few bucks, I tried removing the old PPF clear-bra myself… and of course, a big deep chip of paint came off right before my son’s big birthday surprise. 😩 I sent Nathan some photos, and he didn’t even flinch. He told me to grab the paint code from the door jamb, get a can made up at NAPA, and bring it to him so he could work his magic. 24 hours later—you’d never know there was ever damage! Turns out, he even researched how to speed-cure the paint overnight so he could safely PPF over the repair. That kind of care and dedication blew me away. He also got us in on a tight timeline, even shifting his schedule around to help us out. We came in for front-end PPF, but Nathan went above and beyond—covering the bumper, half the hood, mirror backs, and even polishing and PPF'ing the headlights! 🤯 As a cherry on top, he surprised my son with a chrome delete on the grille—and it looks amazing. The flat black vinyl totally transformed the look of the car! He then even detailed the car!!!!! It looks like new! This level of pride, craftsmanship, and kindness is hard to find these days. We’ll definitely be back for more work at Redline Concepts!

Far and away the best PPF install I've ever had on a vehicle. Nathan is on another level. His attention to detail and extreme care resulted in a practically flawless install. I've historically had bad luck with PPF installs (debris underneath, peeling edges, bad cuts etc.) and inevitably ended up regretting the money spent. Nathan flipped the script on that. He is now the only person I'll trust to do my future cars and I've already recommended him to a few others. If you want cheap, look elsewhere. If you want it done right, this is your guy.
