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.
