Got my girlfriend a lovely little Raleigh 20 and I've stripped it down, there are areas that I feel will be hard to get paint to and was wondering, I can't remember what its called but using positive/negitive charge spray paint is attracted to surfaces....
If i crocodile clipped negative from weak car battery to rattle can and positive to frame of bike would this work?
This is a stupid idea and even if it would work I'm prob not going to do it but i'm curious?

I would think you would need a spray gun that can electrically charge the paint drops coming out.
So i would think it wouldn't work! Could be wrong tho.
Have you thought of getting the frame powder coated?

No, it wouldn't work. You need many many thousands of volts to cause any attraction. Nice idea though!

Ok was an idea, I think what I'll do then is hook it up to the mains, is it brown or red that makes you dead?*
*yes joking
Powder coating is an idea but I'm working on a budget,as in I don't want to spend any money.
Thanks

powder coating is pretty cheap really. if you use a colour the powder coaters use a lot and ask them to bung it in when they do that colour it won't cost much.

Yeah, as kee said. My mate gets stuff powder coated for cheaper than it would be to buy the rattlecans! He paid about £20 for a full car roll cage. But it's got to be black, and only when they haven't got a full oven.
If rattlecanned a few bike frames and it's not that bad really. I found that degreasing them properly was more work than getting paint into crevices. I just did the awkward bits first (around the bottom bracket mainly) to get some colour on.
A rattlecanned bike frame will look nice for about 2 weeks before you scratch and chip it to death though - its nowhere near durable enough.

^ yep. Rattlecanned bikes get messy quickly, even if you take care of them.
Powdercoat is pretty cheap, there's a place in Colchester that'll shotblast and powder a bike frame and forks for £30. It's so tough you'll dent the tubes before you chip the paint!

JM2PW, I would imagine the results would be quite spectacular if/when, with all that solvent in the air, you got the can too close to the frame and generated a spark !!

it would be lots better to get it powdercoated

What a coincidence, we did this in a physics lesson not so long ago.
You need a spray gun which charges the paint droplets as they leave the nozzle, and something to give the frame an opposite charge. A car battery wouldn't be enough, as many thousands of volts are required, as stated above.
+1 to the powdercoating idea.
