YouTube - Water Behaviour on Different States of Paintwork



This video shows different patterns of water repellency on three states of paintwork:



1st state: Levelled paintwork with wax. This panel has least exposure to environmental attacks such as UV rays and acid rain. The paint has been fully compounded and polished and protected with Duragloss sealants and spray wax. The detail can be seen HERE



2nd state: Waxed paintwork with contaminants, ingrained dirt and heavy waterspot etching. This panel has also been fully compounded and polished, but is exposed to the environment most of the time. The paint is constantly bombarded with hot sun and heavy rain. This accelerates the waterspot etching process. As a result, this panel is heavily water spotted, has ingrained dirt and is contaminated as it feels gritty. Although the sealant/wax on the surface is still repelling water, it doesn't sheet off water cleanly, leaving drops of water behind. This is because the waterspots in the paint 'grabs' the water as it is being sheeted off.



3rd state: Levelled paintwork with no wax and no polishing oils. This is the same panel as the second state, but after polishing with Meguiar's SwirlX to remove waterspot etchings and any ingrained dirt. It is then washed with a basic car shampoo to remove polishing oils. This state shows that levelled paintwork in itself will sheet off water very cleanly.



The ideal state would be the 1st state.



So the next time you wash your car, try to notice how your paint repels water, if it repels water like the 1st state, then protection is good. If it repels like the second state, it is probably a good time for a polish and wax session.



Of course, these are only my observations and could very well be wrong. Please correct me and feel free to point out to any mistakes or ambiguity.



Thanks for looking!

I like this a lot. Very well done video...I like the music!



I also really like the description of "unclean water sheeting" to describe the water on the etched paint.
 
Awesome awesome awesome vid! You're right on the leveled paint, it's one of the first things I noticed when I began polishing paint. It almost makes you want to let it be, haha. Thanks for taking the time to make this!
 
Maybe I am not getting this here....



to the normal viewer, 3rd state would be the ideal...polished, but NO wax!!!! it has the cleanest sheeting and ZERO water spotting! The first also has un-uniformed beading...imagine that drying! A tight beading finish (wash) would prove there is a much better protection layer on the car!



I have to assume you just finished the car and took video, so the wax isnt setup and bonded to the paint quite yet...



just my 2cents

Let me first say that I agree with what you're saying. I'm not sure what it is about a polished and waxed, or a clayed and waxed horizontal panel that makes it do what it does in the video. One would think that a polished and waxed part would sheet like #3, as you stated.



The thing I've never understood about sealants/waxes is this...One of my cars is wearing two one-week-old coats of M21 2.0, and it seems that my sister's car, which hasn't has any form of protection, is sheeting the rain better than mine! (there was a recent thread on that) My car's a frost magnet when it's waxed with these temps too. Even if you look David Fermani's Opti-Coat thread, you'll see pics of frost and water beading to the half of the car that was treated, while the other half appears completely clean. What gives?

Thanks Rob! For the music, credit goes Rickvanman, I just used one of his free royalty free music.

Hmmm, polished but no wax is ideal for water sheeting, but probably not so ideal in the real world since there is no protection?

I guess we're looking from different point of views...



What you said is true about the 1st state having un-uniformed beading. If I recall correctly, the LSP used was a sealant and was topped with DG Aquawax, so I wasn't expecting any super uniform beads as well. Drying it will be quite a pain, haha.



Regarding your statement: "A tight beading finish (wash) would prove there is a much better protection layer on the car!"

I'm sorry but I have to agree with only half of that. I did a mini-test about 2.5 years ago of M21 1.0 vs Soft99 Fusso Coat HERE



It's probably hard to tell from the pics but I firmly believe that beading is not an absolute indicator of protection. The key word is absolute, it may be indicative, but not absolute.
 
right, but a beading shot like this shows there is good protection (I did that truck two weeks ago with clay, polish, DWG, BFWD

the thing about it, you DONT want beads to dry like that, but with it beading like that, a simple washing SHOULD clear it all up since its just on top of the sealant and not on the porous paint... if it was bare paint beading like that, then there would be some etching going on for sure...Ill have to go check my car outside during this rainy week to see whats going on, I havent applied wax on it since last summer, but I have clayed it twice since, but ZERO polishing or protection added
 
Hi toyotaguy,



I'm sorry for my confusion. What do you mean by we do NOT want beads to dry like that?



You mean if it is sitting outside in the rain, we do not want it to dry because it will leave water spotting, hence, state 3 would be ideal because it will sheet water away cleanly, leaving no water spots on the paint to get etched in?



If it is so, then I will also agree with you. It would be better if the paint is protected and yet, sheets water away such as in state 3. Ahhh, I think I get where you're coming from now...



Then, will I be right in saying that if one would prefer water sheeting such as in state 3, one would generally use a sealant as the LSP, as opposed to a wax, which beads rather than sheets?
 
I find that the clear coat itself and the contour of the bodyline also affect water beading.



On my 2000 Nissan Maxima, no matter how much I level the paint with expensive polishes, IPA wipedown, boutique waxes, it does not bead as well my other black cars that receive the same detailing treatment.
 
First, very nicely done video. Kudos!



On my car I use Klassie AIO and follow with SG, letting the SG sit overnight to cure. I find that with the sealant I get a nice amount of beading. While my car is parked outside at work, rain leaves a lot of beading, then the wind carries dirt that accumulates on the beading. If the beading evaporates, the dirt remains and my car is covered with bead sized dirt spots. The cars next to me, which are not protected, look a lot cleaner since a lot of the water sheets away instead of beads. It's frustrating spending time protecting the paint and ending up with a dirtier car than doing nothing at all... but at least the paint is protected.
