Beading & CQuartz Question

[newb001]

2 part question:

1. What's the point of beading if I just end up with water spots where the beads were (this is a few hours after a light/moderate rain, the wet spots are just drips from the roof):

The tight beads that my car had looked great/cool, until they dried...

2. Should CQuartz in particular not be doing this? I know it was discussed in another thread but I wasn't sure what the final answer was. Is it supposed to create spots like this but with the CQ it's easy to remove at my next wash (or perhaps with a QD or some opti-clean)?

Car was washed a week ago and hasn't seen any rain since (until the photo yesterday). Just some dust from our parking garage. Overall, before the rain, the car looked spectacular. Now the entire thing is covered in these spots. I was checking out every other car I saw today and none of them had anything like this (even cars that I know were our in the rain yesterday).

Thanks for any help.

drive faster to make the bead come off your car!!!

rain has too much contaminate/mineral causing those white spots

Some white vinegar will knock those out. You should never allow rain water to dry on the surface: regardless of the LSP. Too many chemicals in rain these days.

Hi
let me explain you little about water beads and Hydrophobic.
in simple words it mean the surface resist water rather than "like" water , the more the droplet is "taller" the more surface is water resisting, see this diagram:

now the whole idea about great coating protection is to make surface as less possible droplets stay on the paint, means great balance between water sliding and hydrophobic on horizon surface.
the pic you show means small beads on surface which are concentrated the water to small round drop, rather than spread it on surface. that why its more noticeable.
wax and sealants make nice beading shots but the they usually stick harder to the surface and not slide off the surface.
when having acid rain or tap water its more likely you will see it . this is very hard to prevent, cquartz is not super hydrophobic coat... there will be always water drops , the question is how many .

we have now solved the problem of removing them from the coat, preventing them to merge in the coat.
so this will be easy to wipe them off well.

Is the new shipment that is due to arrive at AG the new formula?

I find Avi's explanation very enlightening.

Thanks for the honesty. Minimizing the amount of water that would stay on the paint to a very little amount is a big help in minimizing water spots and etching. We can't always be there to immediately and safely wipe our cars dry. :xyxthumbs: to CQuartz.

yes!

yes , exactly, the idea is >>
less droplets >> less water spots>> less wiping off etching>> less marring the paint= less swirls.
you should all look for more sliding angle droplets , not only nice beading drops.

i wish i could make cquartz super hydrophobic... but its impossible to make a durable coat.
