Collinite No. 845 - Insulator Wax

Collinite say No845 Insulator Wax is their best selling wax, we use this a lot and we understand why. Collinite no 845 Insulator wax is the liquid version of Collinite 476s. Insulator Wax started life as a protective wax for electrical power companies. That goes in some way to explain how tough and durable no 845 Insulator wax is.

Collinite no 845 Insulator Wax leaves a tough, protective coating that more than stands up to all that nature can throw at your paint.

Used on a clearcoat and no 845 Insulator Wax gives you a high gloss, wet look. This wax is better suited to lighter paint colours and those wanting maximum durability.

No. 845 Insulator Wax is semi solid in the bottle, shake for about a minute and watch the wax loosen, it's then ready to apply, can be used by hand or with a machine polisher.

Our reviewers love this wax with one adding that No 845 is 'by far one of the best waxes i have ever used'.

Our Take

“One of those products we’ve trusted for years and still reach for today.”

No. 845 Insulator Wax is genuinely one of our all-time favourite products. It’s been around forever, it has a huge following for a reason, and it continues to prove itself year after year. With well over 70 reviews backing it up, it’s not just nostalgia — it delivers.

In terms of finish, 845 gives us that classic carnauba warmth but with a sharper, glossier edge than many traditional paste waxes. It brightens lighter colours nicely and adds depth to darker paints without looking heavy or overly oily. The liquid format makes it much easier to apply than a hard paste, and when we keep it thin, it spreads effortlessly and buffs off without drama.

Protection is where it really earns its reputation. Durability is outstanding for a wax — especially considering how easy it is to use. We’ve seen it hold up extremely well through poor weather, road salt, and regular washing when applied to properly prepared paint. Water beading is tight and consistent, and maintenance becomes noticeably easier.

For us, 845 sits in that rare category of products that combine ease of use, durability, and proper wax aesthetics. If we want long-lasting protection without stepping into full coating territory, this is still one of the most dependable options we know.

“Whilst this product is disappointing in the aroma department, it just smells of chemicals, it goes on very easily and gives amazing beading. I only used it last week on a Polar White Mercedes, having first used the PoorBoys World White Diamond Show glaze, so I'm not sure how long it will last. Still, easy on with a machine polisher and easy off with a microfibre. I like it.”

“This is the first wax I've used, and I was really pleased with both the application process and the results. I applied using a DAS6-Pro and Chem Guys wax pad and buffed off residue easily with a seamless microfibre towel. On top of many hours of polishing the results were amazing. I've just washed my car a couple of weeks after the marathon polish&wax session and wow, I wish I'd started waxing it earlier. It's almost as shiny as when I first polished and waxed it with just a single wash. Some minor observations: The bottle is not very practical, I've dispensed it into one of those burger van sauce bottles for future use. They say you don't need much wax, and boy are they right. Took me a while to find the right amount, but even when I'd gone way overboard to begin with it wasn't hard to take off. Not sure how many lifetimes I'll need to get through the whole bottle...”

“Over the years I have tried many waxes, mainly expensive ones which I still have, however, none of them match the durability and gloss wet look this wax offers, very easy to apply, very easy to buff off, no white streaking, and fantastic results, I use this wax not only on the body panels, but wheels and plastics too! This is by far my favorite wax, I've had the same bottle for nearly 3 years now with still loads left, well worth the money and one I will certainly be buying again, if it ever runs out!”
