This Thread I find very interesting. I never knew that automotive paint needs to breath. Never thought about it, but it makes sense. I'm awful about washing or waxing/polishing a car. But when I do I have used NuFinish for years now. I have used other polishes that cost more but I think NuFinsh did as good a job & held up as good as any.
This thread has given me a good reason to do nothing but was our new Equinox for sometime. LOL
I have been on the CORVETTEFORUM for almost 20 years. The corvette owners like to use stuff from www.Zainobros.com I have about 15 show trophies for my corvette. The finish looks like its wet and it lasts for over a year. Check it out!
It's funny if you go back and read this entire thread, because basically every single wax made has been touted as "The Best". It just shows how subjective this subject is. Most products are really good now. That being said, this is my current routine.
Spring, Summer, Fall = Meguairs Ultimate Fast Finish because its stupidly easy to apply and it is a true paint sealant, not a wax. I can do my whole Terrain in about 15 minutes. I will then strip it off about once every month or two and reapply, that way I don't have to guess how much is left on the paint and I will always have maximum UV and fallout protection that is possible with a sealant. That may be overkill and wasting product, but the stuff is so cheap anyways I figure why not. Also, it doesn't matter what wax or sealant you use, if you live somewhere where you are prone to getting bug splatter on your car, the bug remains are highly acidic and will blast through your sealant in a matter of days if you don't get them off. if you leave the bug guts on for too long they will etch your clear coat. Most wax sealant claims are based on "best case scenario" situations. see this post from Meguairs themselves. https://meguiarsonline.com/forums/sh...l=1#post385550
Winter = Around November when the car washing season ends I will clay if necessary then apply Klasse AIO then top it off with Klasse sealant glaze. Klasse sealant glaze is a notoriously known for being a PITA to remove and streaks, but it's durability is unmatched. Only a few other products on the market can match its longevity. This is the only combo I trust that will truly last through a harsh winter until late march when I can start over again.
In the end though, this is just my routine, do what works for you
I've always used cleaner wax without a glitch. I am looking to try something else that is less time consuming. I typically do it twice a year, spring and fall. The trans am was all by hand everytime, the vue and terrain 6" orbital.
FWIW, I always wax [Collinite 845] my new, freshly washed cars. Two coats. Pros - Increased resistance to minor scratches; easier brushing off of snow and ice; easier washing [by hand]; and it looks good, too. Plus, call me crazy, but I like to wax the car. Cons - until I read the "paint must breathe" story, never a problem. Now, after two harsh Northeast winters, I'm waiting for the cracking. Rain still beads nicely, though. YMMV.
I think, based on what I read, what it really means is new automotive paint needs a time period to fully cure. After which any out gassing of solvents slows to near zero.
Which is why they say not to wax or seal paint on a new car until after 30 to 90 days. It may depend on when the car was built . .. winter or summer . . . and how long it gets to sit in the sun and "bake".
I have never worried about it since I do not remember applying wax or sealer until +6 months or more.
I've used Meguair's Sealand 2.0 followed by Collenite 845a day or two later.
