I was watching overhauling a few years ago and saw Chip Foose do an awsome paint job that looked like it had water on it. I can't find a video of it anywhere. I know he sprayed a base coat, and at some point sprayed water on the car and painted over it. I just don't know the whole process. The effect was similar to the jayracing rain drop valve cover. Does anyone have any idea how to do this? Sorry if I put this in the wrong forum. I thought there was some type of custom paint forum but I haven't been on for over a year and couldn't find it.

I belive they throw a layer or two of paint, then they put water on the car. Now you can use a spray bottle or just throw water however you want. After the water is on the car you spray the last layer of paint and what till the water has evaporated and throw the clear. Not that sure but that would be my guess.
 
you paint the valve cover the color you want it then you use a spray bottle and spray the cover with the water creating drops you choose the size (small dries faster). Now that the water is on it from an angle 45 degrees or less (from the side across the panel) you spray a contrasting color (some thing that will stand out from the first color you sprayed). then comes the hard part you have to wait for the water to COMPLETELY evaporate. then you can clear coat it. The reference photo you used the painter used red as the base and black as the contrasting color
 
I'm not a big fan of a lot of those custom paint styles but this looks very nice. Moderation would be key though IMO. It's ugly when everything under the engine bay is painted but this is a nice way to accent a valve cover or something.
 
man when I read your title really fast I thought you meant how does rain effect the color of paint???? Like acid rain and stuff like that.
After reading other post I then realize you meant "how TO paint the rain effect."

That's pretty cool looking. Crap now I have another idea that I have to decide on...
 
Thanks 2gGSXEclipse. And to everyone else with helpful input. I looked for a long time and only found brush techniques and photoshop stuff.

I'd also like to add. I do remember when Chip Foose was painting the car on overhaulin' he used compressed air to blow the water then paint over it. When he finished it looked like the car was moving. Pretty cool.
 
no no adverse effect on the paint, as the water is completely evaporated before clearing. Here is a how to on this subject..







Now, materials used are:
Adhesion promotor (AP01)
Kandy Apple Red Basecoat
HOK White
HOK Black
UC35
SG100



First...Scuff the material and then put a coat of Adhesion promoter on it.



Next...Spray your basecoat. personally i feel that if the color is a lighter color then the drops will be seen much easier...but everyone has their flavors so to each their own.

Next, you'll take a water spray bottle (any type works...dollar store has them usually 2 for a buck). Biggers ones are a buck each. This part can be the frustrating part...as some water bottles will spill out big droplettes onto your surface if you're not careful. Find the sweet spot where it sprays a good fine mist, and then hold it about 2 feet (at least) above and a foot or two back from the object you're spraying . The mist will start to fall and you'll see TINY droplettes. Keep going till the dots get to be a good size that you like and can see.

With this...if you get a BIG drop somewhere...it can be an easy fix.
Take a paper towel or napkin...twist a corner up, and take the point of that corner and put that point into the BIG water drop. it should soak it straight up. You really should only use a corner once as it won't soak up very well after the first one usually. You can tear off papertowels into 4-6 inch pieces as well for this...just depends on how well you spray the drops.


Now, with the drops on there...You'll take your object and face it sideways (i choose shooting perpindicular to the length of the cover) either width wise, or lengthwise. Load your airbrush with either White, or a mix of mostly white with a couple drops of the base color. This will give you the light side of the drop (reflecting the light source).
Here, I'm usually around 6-10 inches away from the cover. You are going to spray as if the AB is just peeking over the top of the cover. You'll need to keep pressure really low, and do this in VERY LIGHT PASSES. Spray until you are happy with the White that is showing on one side of the drops.

Next, turn it around so you are shooting from the opposite side of the object. Now, you'll take your basecoat and add a little black to it. (Since black kills colors...I'll add it with either a toothpick or just ever so slightly squeez the color out, and try to break up the drop using the edge of the AB top feed cup). it doesn't take much to darken it, however it also depends on the size and how much paint you're gonna use.
Spray this the exact same way you did the white.
You can move left to right, and you can slightly (VERY SLIGHTLY) raise it up a little higher to make sure you hit the drops further back from your spraying point. You don't want to get too high, otherwise the black and white will mix and now you're looking at a blister, more than a drop.


Now, this needs to dry. I don't use anything other than one of my work lights (and that thing gets Really hot) to just project light and some heat to it. I'll place it under the light and leave it there till all the drops are dry



Once all the drops are dried, it's ready to be Cleared.
DO NOT SCUFF AT THIS POINT...YOU WILL REMOVE YOUR DROPS!!!!

I've learned that you have to have a really wet coat. Watch for runs...don't make it that wet...but you do have to make it wet. I put on 2-3 coats. Let dry overnight. Then I'll wet sand it with 800
1-2 more coats let dry overnight
Wet Sand and Buff


I hope this helps,

Any questions, don't hesitate to let me know!!!
 
exactly how it sounds. spray two coats. then get a windex spray bottle full of water and spray on. then spray another coat on with clearcoat
 
thats kinda cool. i feel like it just makes the valve cover look kinda dirty though
 
That almost looks like it's been Hydro Dipped. I'm about to hydro dip my car's engine cover, intake manifold, and intake. I am also gonna dip my entire interior.

On a side note, I need to know what would happen if the top part of my dash gets wet? (The parts that's not plastic) Will it warp?
 
that would be sick if you did the intake manifold too and then used air to make it smaller to larger drops so it looked like it was moving and the water was beading off
 
put water in a spray bottle after prepping and painting the surface the color you want. spray the water on the surface so that you have drops on it the size you desire and spray light coats at an angle to lightly mist around the dropplets of water. let it dry and clear. . .good to go my man.
