Used this now in harsh upstate NY for four years and it lasts amazingly long. I wax twice a year and this stuff just lasts and lasts and lasts. Excellent product. Definitely heat it up in hot water before you use it, and shake vigorously to get everything mixed together before applying.

Best product I've purchased for vehicle care! One bottle did an F150 4X, three autos and one SUV-for less than $20. Prep the surface well, remove all water spots and apply 845 in a thin coat. will last at lesast 5-6 months as identified by water-beading. For an even deeper shine, apply a quality wax on top of 845, but it's not necessary. Apply only in shade on a cool surface. Vehicles will look 'just washed' even after a drive in the rain.

All I can say is wow. The product was amazing. After washing my vehicle and drying I placed the bottle in hot water to begin the process to mix the product into a thin liquid. The heat from the warm water melted the wax into the solvents that are in the bottle. Then shook the bottle until I got a thin consistency. Once this was done I then proceeded to prime my CCS foam Lake Country Pad 5.5" red pad. Once primed I put 4 dime sized product on the pad and proceeded to application of the product on speed 3 of my flex 3401 dual action polisher. I applied the wax to the complete vehicle. Applying only minimal product to,the pad as needed. I let the product sit on the vehicle for 30 minutes from the start of the application. I performed a swipe test and got a nice shine line from the swipe test. I proceeded to remove the hazed over wax with a soft microfiber towel buffing to a fine shine. All I can say that a little product goes a long way. Use about 2 oz of product to do entire vehicle.

I will be doing a complete detail on this vehicle over the Thanksgiving weekend. On this detail it will include a two bucket was, clay, two bucket was , polish, sealant, and two coats of Collinite 845.

One good thing was the discount that I got when I purchased the product from Detailed Image.

if you want a durable wax this is it, last for months with a nice deep shine.

A little harder to remove than 476 but seems to last just as long. Just be sure to only apply a little to the pad as a little goes a long way.
