Does latex and cars mix?

[Red]

An idea for a shoot I've had today requires painting body latex onto a car, but I'll only do this if it will peel off as easy as I think it should.

Thought I'd ask all you wiser and more experienced people in case someone knows for sure

as long as it isn't my car, I say go for it...

My thought would be it would probably peel off the paint pretty easily, especially if the clear coat is new and in very good shape. However, also remember that there are many crevices, seams and irregular surfaces on a car so be careful where you put it as you may be picking bits of latex out of it for a long time to come. Also I'm assuming the body latext you plan to use is the type you use at room temp, not something that has to be heated. If it's hot I would be a little more worried about what it would do to the finish.

All that said, I in no way claim to know for sure. There could possibly be something in the chemicals of the latext that wouldn't play nice with you car's paint. If I were you, before I tried this I'd do a test on a unexposed panel such as the underside of your hood or something.

It might not stick if the cars been waxed.

Thanks for the advise guys.

If I absolutely felt compelled to do such a thing, I would first make sure the paint on the car was in good shape. Any porosity in the top surface would be something for the latex to latch onto. Then I would put a heavy coat of wax on, preferably silicone based. I would use a semi-gloss latex. It tends to stay rubbery longer than flat wall paint. Finally, I'd get a drying retarder....whatever they sell that slows down drying time.

A necessary precaution would be to try this somewhere on the car to see how it works. I'd pick a spot that doesn't show in case it goes badly (like the inside of the trunk).

BTW, it's not polite to say "drying retarder" anymore, we say hydrophyllicaly challenged.

Well, that's a relief. I was really getting nervous about the possibilities....

They also sell an automotive paint product called fishe-eye eliminator. I imagine that must be driving the PETA crowd nuts. :lol: :lol:

First off I wouldn't put it on the car to begin with. Secondly, if you wax it and then put the latex on, you will get what is known as "fisheyes" all over the place. Even if you don't put a fresh coat of wax on, if there is any wax at all you will get fisheyes.

Tom a silicone based wax will only compound the fisheye problem. There is a product called that goes by a common name of Fisheye Eliminator that you mix with the product. However, I am not sure it is compatiable with a latex product or not. See your local auto body supply dealer for details.

I suspect that this is one of those really great ideas that turn out to be a really bad idea!

Yes indeedy I am.

The idea is to make it look like the car is being painted with regular wall paint.

[Jon]

Maybe use masking tape and paint directly onto that? Or get a washable paint - theatre techs often use this kind of paint, but I'm not sure how it would stick to an automotive finish. I know there are some wash-off paints used for aircraft (RAF paints white on their A/C for winter exercises and vintage aircraft are frequently painted in temporary colour schemes for filming).

[Red]

There will be a model too, so scale is important.
This temporary paint is interesting. Will investigate that

[iwatkins]

Temporary paint ?

Anyone remember the opening sequence of "The Cannonball Run" ? White Lambo gets hosed down and turns back into a red Lambo (or the other way around). Sounds like all we need is a Lambo and two hot chicks in tight shiny jumpsuits :)

[Avalonthas]

Shouldnt have problems with it. Give it a try. I think the most damage it will do is small peelings of the paint where there is already a scratch or scuff. Nothing some touch up paint wont fix.
