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

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.

The instructions on Autogeek's web site says to remove it before it completely dries.



"You will find the wax easiest to remove if you apply a thin coat and do not let it completely haze over before buffing."



I thought is sounded kind of odd, too.

The 845 directions say to "Allow to dry to a haze and then polish off...."



I apply 845 with a PC to the whole vehicle before I start removing. That's the same method I use for almost all of my LSP's (including Collinite 476, Megs #16, etc.) and I've never had a problem buffing them off.
 
845 was changed a few years back..maybe 3 ...due to VOC regs...there is a post on here some where to tell whats the new one and old one...something to do with it saying paste on the bottle...maybe the new one is better or vice versa...search for the thread as it was discussed which one seemed better...



AL
 
I can vouch for 845 lasting four-five months.



I put a coat on my car before winter, and it was still beading a month AFTER winter.



This is my go-to wax for winter prep.

Yep, same here, and I even let Souveran dry before I buff it off; I wait until the LSP will pass the "swip test", where it wipes off clean and dry. I've left all these LSPs (Collinites, #16, Souveran, you name it) set up for a *long* time, up to several hours, and they all buff off easily as long as I don't put 'em on too thick.



I sometimes think that vendors might suggest methods that are easiest *no matter how you do it* so that people think "gee, easy to use, I'll buy more", and if those methods result in people wasting product or getting compromised durability well... hey, the customer will just be buying more wax (and sooner).

Yeah, the *post*-VOC bottles say "paste wax" on the bottle. I've done side-by-side comparisons with pre/post-VOC 845 and I couldn't discern *any* differences at all; they behaved exactly the same in all respects.
 
If you are applying 845 by hand....is a foam applicator or microfiber pad better to use to get a thin coat?

I like foam applicators personally.



In my experience with 845 it lasted reasonably well on garaged cars, not so much on outdoor cars. On my car I got close to 3 months, but my car sees a wide variety of weirdness. Nothing seems to last on it. :/



So far, oddly, the best durability I've had with anything on my car is #16.

The first time I used 845 I was disappointed by the durability. Second time around I let it sit for 30 min and it worked much better. I put a coat on the Sierra for the summer back in May and it's still beading quite nicely except on the hood. I think the heat may have killed it fast there :nixweiss The truck does get garaged often but washed maybe 1-2 times a month.
 
I used a clay bar, then polished. Put a layer of NXT2 on and let it cure for 24 hours. Then put a layer of 845 on. Beading is less than average on hood, almost no beading on roof, and is ok on the sides of the car. This is after about 3.5 months.
 
In our situation, 845 lasts ~4-6 weeks (max, more like 4) on a car kept outside 24/4. FWIW, the car was fully prepped before application. IME, the 476S is much more durable.

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

o.k.. yesterday i finally did my wash, clay, wash, megs #9 (by UDM/orange pad) and then 845 x 2. the car (white diamond CTS) looks great. i applied by hand with a micro covered foam pad very, very thin wiping after each section then went for the second round. we'll see how this application holds up! :soscared::chuckle:

Maybe affected by the NXT under it. I find 845 is most durable when nothing under it and 845 x 2.

I've just figured that out myself. I had tried 845 over various polishes,but it didn't last nearly as long as it should IMO.



I put a coat on in early March,and it was totally gone by the end of June. I applied a coat of 845 on top of the paint without any kind of polish on it. We had a lot of rain shortly thereafter,and then I had tons of tiny little beads. I added a 2nd coat last weekend so I should be set for quite sometime.



BTW,I've never seen beads that small and tight. I've never seen beads fly off a windshield like they have done with the last two coats of 845.
