Topping Megs #21 sealant with Collinite 845 opinions

So I have been contemplating getting some Collinite 845 for a Winter LSP as I have heard numerous good things about it's durability. Until now i have been using Megs #21 and while I very much like #21, I'm not too sure it's giving me lasting protection throughout the winters here in Minnesota which can be long and brutal. I need something that is going to last 5+ months at least and was curious if anyone had any opinions on topping #21 with 845 for added durability or would just a couple coats of 845 by itself after a freshly clayed vehicle be as good or even better??
 
fordf150- I find 845's durability to be inconsistent; sometimes it's *wonderful* but other times it's just not :nixweiss



If you're dissatisfied with your M21, then yeah, I think you oughta look into some other options. But I'd probably lean towards topping it with Collinite 476S paste wax instead. That stuff *does* last a good long time (for me) no matter what the application.



FWIW, the best durability/protection of all IME is heavily layered KSG. I've never had anything last/protect as well as six layers of that stuff.
 
If you polish the paint properly, the 845 will last at least 5 months. I've had this happen the last two winters. I live in Northern Ohio where we get harsh winters too.
 
Ive used the Megs #21 845 combo a few times,without dissapointment and I usually get 3-4 months out of it,thats all I really look for by then Im ready to do it over again anyway

Not always ;)



I've played around with this a fair bit, on the primary winter-use vehicles. Did side-by-side comparisons.



The 845 *usually* lasts great, but there are some seemingly inexplicable cases where it simply *doesn't* :nixweiss I can't figure it out- identical prep, identical treatment, no obvious reasons why it fails when it does.



Sorry, don't mean to sound all :argue I just don't want somebody to think that 845 is an air-tight, guaranteed-to-last solution (even if it *is* holding up super on my beater-Audi ;) ). I've had it die off completely while the 476s on the other half of the panel was still going strong.



Glad it's working out so well for you though. When it does work out it's a great LSP.
 
Thanks for the tips fellas.



Accumulator, The main reason for my using 845 besides Collinite's reputation for durability, is 845's ease of use. From what I understand it is much easier to work with than 476 paste wax and almost as durable.



Accumulator during your trials now many coats of 845 were you applying? Since it's a pure wax wouldn't several be better than one??



Now don't get me wrong, I love Megs #21, very easy to use and does leave long lasting protection, especially when used in conjunction with Ultimate Quik Wax as a booster. I just don't think it has the ability to get me through the entire winter and early spring up here. I usually try to apply my Winter LSP in early October or when the temps are adequate. I then may not be able to do it again till April or even May so there's a 5-6 month gap where I need decent protection.
 
If you're looking for better durability, why not do two coats of 845, or 915. 915 looks decent, and lasts quite a while.

Can't argue with 845. Unless your situation is one of those weird ones that I've sometimes encountered, then sure, just stick with 845. Plenty of people are perfectly satisfied with that.



I *do* find that 476S is significantly more durable *for me*, but well...that's just me.

IIRC (not sure I have the notes, this was on my beater-Blazer, which I've since sold), I used three coats, *maybe* four. Definitely more than two.



I'm not 1000% certain that any Collinite stuff layers as well as we'd like (*especially* the pastes, unless you spit-shine), but *IMO* 845 does hold up longer/better with multiple applications.



My current Collinite regimen (after struggling with pseudo-holograms when trying to layer 476S), is a 845/476S/845 "sandwich". I'm *VERY* satisfied with this combo and I then just refresh the 845 as needed until marring/etc. motivates me to start over.




..I usually try to apply my Winter LSP in early October or when the temps are adequate. I then may not be able to do it again till April or even May so there's a 5-6 month gap where I need decent protection.



That "sandwich" approach has lasted through winter just fine for me, but again, that's just me. For one thing, I'm retired and thus not doing the big commute thing every day.

I've never used 915....any issues with pseudo-holograms/solvent-action when doing multiple coats?
 
JohnKleven- OK, roger that, thanks. I'm just paranoid about that after what happened a few times with the 476S (which never gave me trouble...until it did).
 
So fellas, how tricky is 476 to apply/take off?



How long before you buff it out? Swipe test? What happens if you wait too long or not long enough etc...



I've never been much for paste waxes, but if 476 is the cat's meow for durability then maybe I should look into using it, along with 845.

If you follow a few simple rules then Collinite 476S is not tricky or difficult to remove.



Apply using a slightly damp foam applicator and don't load with too much wax. Apply as thinly as possible and don't do more than one panel, or maybe half a hood, at a time. Use the finger swipe test to ascertain when to remove and note that this could be within 5 minutes, in my experience, on a nice warm/sunny day. If the wax has been applied too thick and is difficult to remove use some quick detailer on that area to assist removel.



Remember the old adage that 'less is more', especially with waxes!
 
fordf150- 476S isn’t as easy as 845, or some paste waxes, but IMO it’s not tough at all either. The last vehicle I was using it on (before switching to FK1000P) was my Yukon XLD, and I didn’t think that was a pain at all.



I do the finger-swipe test. If you do it too soon (and/or try the W-O-W-O method) there are no problems, just a slight decrease in durability. If you wait a long time it’s not a big problem like it can be with some products (at least not IME).
