I disagree that coatings are as inconsistent as one post mentioned. User stated above that beading and sheeting were the reason he thought the coating was gone, but that his car still cleaned well. The coating is in tact as it should be. It's just an adjustment regarding user misconception. Use a microscope and I would bet my bet my stock of Collinite that the coating is still there. Beading and sheeting were a great feature of Turtle Wax Ice...ask people around here what they think of those product's durability, dust attraction, and cleanability. I'll state this fact again, cleanability trumps beading and sheeting on any day that ends with a "y".
I respectfully disagree. You have no idea if the coating is still there. How can one person use coating X and get excellent beading for 2 years - and another person use coating X and get no beading after a few months and you still believe beyond a reasonable doubt the coating is still there???
IMHO the coating is gone.
People like to say the "coating was contaminated" and they "brought it back" (and saw beading) after some high pH / APC style wash. IMHO, this is just not true. Aren't coatings supposed to have LESS stuff stick to them than "wax"? Aren't coatings supposed to repel dirt? Have you ever heard of someone whose Collinite's beading mysteriously disappeared and the had to restore it with APC or they washed it with the "wrong soap"? No.
What these people are seeing after these strong washes is healthy naked paint's normal beading. Clean and relatively defect free paint will be fairly hydrophobic with no LSP on it. Just read through this thread and see the myriad of experiences with coatings. The reason they behave so differently is because some coatings are still there and some are not.
Measurement of "ease of cleaning" or "cleaning well" is sooo subjective. In fact, I've never seen a car that was difficult to clean. Decontamination and correction are different. Cleaning? Use any carwash soap on any car in a single bucket method and the car will be "clean" (above surface contaminants removed). This is regardless if it has a wax, sealant, coating, or no wax on the paint.
I just think coatings whose mysterious hydrophobic properties that come and go are a crap shoot. I say if it doesn't bead - it's not there. Wax always beads if its there after the paint is "clean". You don't need special soaps, boosters, or APCs to prove it.
Why do some peoples coatings fail and others do not? Dunno. Mystery.
For me beeding and sheeting go hand in hand with self cleaning abilities.
Agree with this 100%. I agree so much that I say those who have no beading - their coating has failed.
I've been using EXO for quite a while now. I've never had a problem with it failing prematurely... I just finished re coating my Camaro after two years with EXO on it. It was still beading and sheeting fine.
It's great EXO lasted so long for you and your happy with the product. The OP's experience was completely different from yours. Again, IMHO - it's a crap shoot.
