Collinite 845, not as long lasting as it's claimed? - Page 3

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

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

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

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?

Have anyone tested how good collinite waxes hide swirls?

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?

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

Very weird

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.

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 put it on my Ranger and my Neon in November, lasted me through the winter no problem on both vehicles...

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.
