Semi OT need some paint advice

[SandiaPaul]

I have a "real" job to paint the interior of some makeup bottles. 300 bottles in 20 colors.
They are plastic bottles and my plan is to pour some paint in and rotate them around to cover the interior. Prob will need 2 coats, I also might make a little jig with a slow speed motor to turn them.

Colors need to be a match to pantone chips, close but not exact.
My question is what paints would you recc? Client is worried about crazing the plastic, as am I.
Also if you have any better ideas of how to do this I am all ears.

Thanks,

Paul

How long do they need to last/survive.....are they for long term, or just a temp display or photo shoot?

I like the idea of swirling them to evenly spread the color.

Are you planning on mixing the paint to match the pantone colors yourself?

If you are using an acrylic or water pased paint there should be no crazing issues.....but it likely will not stick well, evenly or for a long time to the smooth interior of the bottles (maybe if some sort of clear coat or clear primer were applied first, that it could bond to.)



Sherwin Williams seems to have a PMS matching system,...so if you had the budget to have them mix you the colors in quarts, of say semi gloss exterior acrylic or such....and then swirled this around in the bottles, it should stick to the surface, and because it is an acrylic it should not craze the bottles...also, because it is a fairly heavy/thick paint, it should cover really well.

....just a thought

Marc,


It is a counter display(rather several of them) and they need to survive for a while, like 1 year or so.
I am planning(hoping really) to pick paints that are close then tweak them to the right colors.
I am afraid of the sticking issues with the water based paints as well. 
I use Tru Color paints a fair amount in my own model work, I will start with that, and see what happens.

Thanks,

Paul

Paul,

maybe you could fill the colored bottles with something like gelatin or so to avoid the color to loosen?
