Tough, Durable All Weather Wheel Protection.

Independently proven to outlast other rim coatings, C5 uses a unique chemical bond to become the functional surface of your rims making them dirt and brake dust repellent as well as being much easier to clean. A single application lasts up to one year.

C5 has a unique, fine surface rheology and chemical bonding mechanism, resulting in an outstanding performance. The former property gives the coating its contaminant resistance, and the chemical bond formed between the wheel surface and C5 makes the coating that long 1 year plus durability.

Gtechniq Alloy Wheel Armour will retain its integrity up to temperatures of 600C, making it suitable for all parts of your vehicle’s rims and brake callipers.

Amazing finish

Amazing finish, very easy to use but make sure you prep everything properly before application. Much better quality of finish if you can let it cure overnight, ideally in a garage rather than outside

So far so good.

A bit too early for me to truly tell yet, but so far so good. I've used it on my hillclimb competition car and the brake dust from the pads used is eating into the alloy lacquer, so if this can protect them then that will be real win. I'll know for sure in about 3 months time!

Great product!

This is a really top quality product,used on a set of fondmetal matt black alloys,follow the instructions carefully and decontaminate the wheels with a panel wipe before application,the end result are wheels that are extremely easy to keep clean ,in most cases a strong jet of water from a pressure washer is all thats needed,I would recommend buying the larger size and treating the wheel barrels as well,well worth it in the long run,highly recommended!

Undoubtedly good

Undoubtedly good but don't spill it like I did. Very expensive mistake.

Hope it works

Bought this to help protect some new winter wheels, watched the video above, cleaned the new wheels with GTechniq Panel wipe to remove any protective coating and applied with the supplied pad, then wiped with a microfibre cloth, difficult to know if I used the correct amount, ended up using half a 15ml bottle on 4 alloys and will use the rest on the 4 wheels I take off ready for summer.

Just applied to wheels of new car in the hope that keeping them in good nick will be easier. Easy to apply after use of Gtechniq panel wipes. However, video advises using a new wipe for each wheel. Why then do they only supply 3? Perhaps this is a cult product for Reliant Robin owners?

Best I've come across so far

Used this stuff on some older but well prepared BMW 7 series wheels about 6 months ago. The wheels are cleaned regularly anyway and were removed for a thorough application to the front and rear of each wheel. So far water beading occurs every time they are cleaned and are a lot easier to clean without harsh chemicals. Probably a good idea to apply to new wheels to benefit from the protection on un oxidised paintwork. A bit tedious to apply on spoked wheels with what seems like women's make up cleaning pads!! Will probably buy the larger size in future for other wheels if the finish continues to hold up.

Superb Wheel Protection!

C5 is simply the best sealant and protection for wheels that I've used. As with all of these things, preparation is key and making sure you have nice clean dry surface to begin with is important. Easy enough to apply and buff off to a brilliant shine. I can be confident that even when I haven't had chance to clean the wheels for a few weeks, they'll soon come up looking like new without too much effort. I use this on both my summer and winter wheels so apply when the wheels are off the car for ease. I can be sure that with one application I will easily get the 4-6 months that I have each setup installed and the wheels are so much easier to keep clean. I buy the larger 30ml bottle so have plenty for two sets of wheels. Well worth the money!

A money and time saving product

I Have just finished my 1st bottle of c5 and I can say its one of the best wheel sealants I have ever used. Wheels need to be prepared with gtechniq panel wipe or similar to ensure bonding of the c5. Easy to apply and no need for strong wheel cleaners after its applied and lasts a year. Just bought my second bottle it will be the only wheel sealant I use on my customers cars. I highly recommend it.
