still undecided on this. will the wind take the magnets off if i put them on the side? same for the clings?

 

Here is a link to a place that actually has vinyl snowflakes. The 3 inch ones are 12 for 20 bucks plus they have 4" ones too.

Thanks, guys. I bought some clings from walmart. Gonna test them out in the next couple days. Then I just need to buy some vinyl decals and christmas lights and I'm all set...

 

I've used tempra paint on cars before, both the brush on and (harder to find) spray on kinds. It works pretty good. There are two big issues though.

1)it can stain the paint. I've been able to remove the staining from a white car by using a decent cleaner wax.

2)you'll want to tape off all door/hood/etc seams, if the paint gets down in there it is a *bastard* to get all of it out again. And if you get a lot in there, every time you wash the car or it rains you'll get some color drooling out of the bottom of the seam.

If you can find the stray-can tempra paint it's really cool. I used to graffiti my car from end to end every week or so. Drive til I got tired of it or it rained, then scrub the car and start over again.
