Collinite 845, not as long lasting as it's claimed?
- Thread starter imported_RedlineIRL
- Start date
I have had mixed results. on my jeep it has lasted a good 5 months with maybe one wash. then 3-4 weeks other times. it has never lasted well on my mothers blackhawk night pearl civic. but I do still love the stuff and use it from time to time hoping for the magic to happen again. It's still one of my go-to's for light silver.

The crappy hot and humid weather here may be it.
I may be going with #16 next time, or even go to Zaino.

The times that I have gotten less than stellar durability out of 845 have been when I used it over CLEAN paint (well maybe not clean, this was before I was using IPA plus other products to prep for LSP).
When I use it over a base, I get much better durability.

I too have had mixed results with 845 regarding durability 
Note that I *always* find two/more layers to work a lot better than just one.
On the A8's rear bumper cover the 845 didn't last long at all.
On the front plastic (or is it fiberglass?) grill surround of the Blazer the 845 lasted for months on end :nixweiss
No, it wasn't a matter of what it was applied over or the application conditions or the shampoo, or anything else I can think of :think: Just seems to work better on some applications than on others.

I wonder if material expansion and contraction plays a role in regards to 845 being able to form a tight bond.

Now there's a thought :think:
The areas were it didn't last long for me were flexible plastic panels (e.g. the A8's bumpercovers), the panels where it *did* last long were harder plastic/fiberglass that (presumabmy) didn't have a flex agent. The latter are more like electrical pole insulators, huh?

o.k.. i've ben using 845 since 1973 (yes, 1973). i have always received excellent durability from this product. last august when i got my CTS i clayed it, applied meg's #9and then one coat of 845. now, here is the test. this car is my DD and its sits outside to boot (in the shade most of the time) and with few exceptions gets washed once a week and blown dry. in february this year i applied a second coat on the top surfaces only (the finish was still beading when i did this). i'm just NOW thinking about another clay, #9 and 845 because the finish is starting to "sheet" a little. what's not to like about this product? :nixweiss

Its a enough to make a satisfied user like me wonder if there are Chinese fake versions of 845 out there

I get 4-5 months through the winter in MN, I just put it on my ranger (DD) on sunday. The EX-P I had on it was gone in a month. 845 should last longer.

Is it possible that putting it on with a machine affects durability? I usually put it on by hand and get 4-5 months.:nixweiss

i agree. heat could be a problem at application. i have always applied by hand.

I think that it all belongs to the condition that the car lives in. In my case I like a car thats clean all the time . There is something cleaned on my car almost every day. My car sits outsidev 24/7, so almost every day its a CCD , Kozak Dry Wash QDs, QEW, and regular washes when needed. Wax on my car doesent last to long, proberly because Im always wipeing it off. Now there is a friend that only drives 3 to 4 000 miles a year, his car is always in the garage , and theres days the car doesent move at all. Im the one that waxes his car, and he only needs it done once a year, At the end of the year his car still beads like crazy , and is very slick. Last year I used D.G.105, and the year before it was Collinite 845. Both waxes lasted a year,but on the average car you wont get any were near that much time.

I don't think so, at least in my case (never experienced a correlation), but *how* the machine is used could make all the difference.

Again, not in *my* case as it was a side-by-side with other LSPs on the same vehicle. And the vehicle where the 845 lasted forever was a beater that went through a *lot* more than the car where it didn't last at all- just the opposite of what one would expect!

Eh..not very well, at least not the 845. Their 476S/885, being a heavy carnauba, will hide more than most light sealants will (and I suppose the 845 does too), but I don't expect any *real* concealing.
No problems here.
I applied it in late October to my (daily driver) 01 Nissan Maxima. Car was clayed and I put on a layer of Klasse AOI. Then a coat of 845. Lasted all winter (car is not garaged) through one of the worst winters we've had in New Hampshire in a very long time.
The car was washed maybe three times the whole winter. It is still feels slick and the water beading is just now starting to dissipate.

I have nothing, but long durability with 845IW, wax in October and still beads in April after a harsh winter car sitting outside 24/7 !
The thing is that you have to apply a very thin film and wait at least 15-20 minutes before removing it or else you are just removing the product.

does it really need 15-20 mins before removing?
I used it the other weekend and did a very thin layer on a panel by machine, then wiped it off. It came off a breeze and has been beading brilliantly in the heavy rain since - it was very warm though with warm panels so maybe dried a bit quicker? Is this likely to compromise durability?
When I used 476 in the past I had to get that off very quick or really pay the price....

I retract my statement of what I said earlier in this thread about longevity of this product. I bought a new bottle of 845 (and some 476) and love this one. It beaded nicely over 3 weeks of mud, rain, salt (beach) and sand. Sheds water like nothing else (cept 476)
