Chemical Guys Bare Bones Undercarriage Protectant Spray, 16 fl oz

I am a professional detailer and in my early days I used to be a CG everything guy but after a while I got tired of trying to figure out which product to use for 15 specific uses, only to figure out they are mostly the same with a different smell. I was using CG tire shine, then VRT, then a satin VRT, then I got tired of not getting the finish and longevity I was looking for. I saw barebones and read the label for a while. Seems like if it is design for undercarriage protection, safe for rubber, plastic, and trim, then it should be fine on tires. Well, this is probably the best tire dressing you will find. Same goes for Adams undercarriage Protectant. Same stuff I think. First it is very oily so if you dont want any lasting stains or slippery spots in your driveway, cover the area or try to clean any spots with a degreaser and pressure washer. Second, you can apply it with a MF towel, tire sponge, or just spray it on. I tend to just spray it on to the tire AND the wheel wells. It’s cheap enough to be liberal with. With just spraying it on, it applies a thick layer on there, let it dry. At first it looks a little streaky as it runs but it dries to a nice even matte finish. You can apply 2 coats about 30 minutes apart if you want more gloss and longevity. Third, the gloss. I dont like super shinny tires. This gives more of a rich deep finish rather than a shine. The way it works is the product seems to react with the oils in plastics and rubbers to recharge it and coat it. It brings out the original natural color plus the spray itself is dark. Forth, longevity. It lasts forever in terms of tire dressings. As long as you properly clean the tires and get them to as “degreased” as possible, the product just clings to tires and plastic wheel wells. Like I mentioned, its like it not only coats but rejuvenated those materials that dry out. On my personal car (BMW M4), I spray the tires and wheel wells with a strong degreaser like LA’s totally awesome or Wolf Degreaser. Sometimes I use a brush to agitate but most times I just spray it of with the pressure washer, let them fully dry, spray this stuff on, wipe any overspray away, let it dry and I’m done. Tires stay rich and dark though about 6 washes if I dont repeat this process and just wash the car. On my client’s cars, the tires and wheel wells stay perfect for about a month of every day driving before you can start to see dirt again. About 3 months before its completely gone. Fifth, is the versatility. I use this for long lasting finish and protection on tires and wheel wells but it also restores and/or protects plastic trim like black plastic Jeep fenders, bumpers, black plastic mirror caps, and various plastic trim. Obviously, its great for all other underbody parts but works magic for keeping road grime from building up on suspension and drivetrain parts. Just be smart where you spray. Out of curiosity, I cleaned and used a MF cloth to apply some to my KW coilovers on my M4 to see if it would keep them clean and debris free. Nothing worse than going to adjust ride height and having your collars seized up because of dirt, rocks, or rust. After 3 months, they looked almost untouched. I just wouldn’t go crazy with the stuff in those areas. Same thing with the engine bay. Need to add some rich finishing details to all that plastic they stick under there now. No problem. I thought the heat might mess with it a little but it was absolutely fine. I also thought that maybe since it was kind of thick and oily that dust would stick. Nope. After it dries, you get real protective qualities and it lasts for about 2-3 months under the hood before dust will start to gather. Can get a little streaky on metal pieces under the hood if you accidentally get some on there. ONE NEGATIVE. You can just keep spraying it on the tires and other rubber without cleaning and it works just fine but over about 6 months, I noticed that my tire sidewalls started to become slightly hard. They weren’t dried out and performance wasn’t impacted. No cracking, splits, or tears but I could feel the product buildup in to something similar to a shell or the hard crystaling of ceramic if left out. hard to describe. Nothing major but on my next set of tires I just made sure to degrease and scrub the tires every 2-3 months and then add barebones and its fine.

I used this product inside the wheel wells of my car. I like the effect...leaves a semi-gloss sheen. Just spray, coat and let it dry...no wiping. The price isn't that bad. This is one of the Chemical Guys products I would buy again.

Works pretty good and has a nice scent. Good product if you're looking for a easy clean up under the hood.

I use this for my wheel wells, bumper grills, and engine bay. Makes any faded or dull plastic/rubber look like it just left the assembly floor as brand new. Black and shiny. It lasts a long time too, my sheen wells still nice and dark and shiny which makes the wheels stand out more. Absolutely love the stuff but I did take off one star for a very common and annoying reason. The spray nozzle. After two wheel wells on a brand new bottle, the sprayer broke. Neither spray or stream would work. This has happened to me with Diablo wheel gel, and speed wipe. Please chemical guys, get your people Who produce your products to up there quality control game and fix this issue once and for all. I’ve seen several other complaints on the exact issue. It’s annoying and I’m sick of Buying empty sprayers to replace your stock junk bottles. Love your products results though!!!

Great product and smells amazing.

I am a repeat customer for this product, as well as several other Chemical Guys products. This is one of my favorites and use it every few months to keep those wheel wells looking great. Just a note of caution if you get a bottle and it doesn't spray well. On my most recent purchase this happened to me (first time actually having an issue). I found that when I removed the top that the tube had come loose from the spray nozzle. Put it back in place and put the top back on...result was product sprayed as expected.

...but the jury is still out. This stuff is kind of thick and has a grape smell to it. I used it on 37" pickup tires and after two coats I had used about 2/3 of an inch of product, which isn't bad. Tires clean and dry. Using foam for application sucked, so I used a microfiber towel instead. Much better. Just sprayed a little on the tires and rubbed in leaving a wet coat on the surface. The finish was not very shiny once dried and had a little streaking in places. This was the first time I had used this product on these tires, perhaps it needed a third coat. Water based, totally dries, nothing sticking or oily. Now, as far as using it on the undercarriage, yeah I suppose it would work. But because of the thickness I suspect you would use a lot of product and you'd spend a lot of time wiping everything down. It doesn't really go on as a spray, it's more like a "globbing squirt". LOL. So it definitely will require wiping down. I may update as I continue to use this product. Update: Just returned from a 1700 mile road trip and surprisingly my tires still look pretty good. Granted, not as good as before I left, but still pretty clean and black. Upgraded to five starts. I like it and will definitely buy again. Update 2: A one gallon container was just delivered. This is the 3rd CG product I've received that has leaked all over the box. Aggravating. I contacted CG about a shipment of Silk Shine that did the same thing and never got a response. But must say, this gallon was just thrown into a box by Amazon and we all know that UPS shows our packages no mercy. Anyway, love this stuff for my tires.

Good stuff, I use on tires

Excelente acabado, lo ocupo para tolvas o partes bajas de chasis, visualmente muy bonito, solo que hay dejarlo secar bien, deja completamente negro el plástico, lo aplico con pistola de aire 10/10, excelente compra

Donne un bon résultat

Super bon produit pour plastique et caoutchoucs, donne un fini comme neuf !

La marca es garantía de calidad, hidrata bien los plásticos.

Like all my chemical guys products i have in my arsenal( and there are many,many)lol it works as described. And as a bonus( and a really good bonus it is) they have videos on you tube showing you how to get the most out of your CG stuff. They also show you in the videos(and it's really not in their best interest)how much product is needed in each situation so you don't waste product and in turn money. Detailing products from any company are not cheap. All in all you cannot go wrong
