truck it

[pistolpete]

so after reading/seeing examples on using kosher salt and hairspray for rust effects, i thought i'd give it a go. couple of lessons i learned use less hairspray but more salt, focus on bottom/lower areas, and WAIT until it's dry between steps.  here's a diecast truck i got from a garage sale for $1, statuesque/pulp alley mini for scale.

I'm planning on using that effect myself soon, thanks for the tips. And that is a very nice car to find for a dollar.

Nice find and even better weathering

Looks mighty good to me!

A mighty effective effect!

The technique is nice, but you need to work on where you apply it. If you look at a rusty vehicle, you'll see that rust doesn't show up as evenly spaced spots like this. Instead, some parts will be heavily affected by the elements (like the top of the vehicle) before the rest of it. This is a well done effect, but the pattern breaks the illusion. Take a look at some reference pictures, and I'm sure the next one will look even better.

@bugpope: thanks for the photo, i did look at some beforehand.  i completely agree i didn't have enough salt coverage and from the blogs/forums i read, it's a common mistake the first time; as is using too much hairspray.   It was an interesting trial of something new for me and yes next time will hopefully be much better.

Don't worry about it, nobody gets absolutely perfect results the first time they try something new. I'm still learning, myself.

Here's a truck I did last year, mostly because painting rust is so much fun.

It also depends on where the truck's being used (or if it's being used at all - that sample image is of a truck left to rot in place). Here in Canada, pervasive winter and salted roads meant old cars would rust from the bottoms, edges, and crevices out.

I had a truck that got cancer EXACTLY like that.  You are there sir.  Congratulations.  I hope mine turn out as good.

I think that truck is an excellent start. To finish it off, I'd take some blister foam, some different brown/orange paints and stipple the hell out of it. Make sure you use varying tones to get a more interesting rusty look.

Here in the uk ,certain models of cars rust in certain places ,front wings on mercs ,around the fuel cap back wings on ford KAs etc. Or due to salt on the winter roads all along the underneath

thanks for the comments everyone.  i do want to clarify something - the rust is not painted over the main color, it's actually underneath.  i've done the "paint rust on top" method before on some hotwheels cars (can be seen on LA post apoc forum) and think those results were good but this was done using kosher salt and hairspray.

first paint the entire thing in rust color and stipple/drybush randomly with orange/yellow/gray/whatever.  let dry then apply some hairpray (sparingly) and sprinkle kosher salt (lots more than you think).  when that's dried, spray the main color and when that's dry, wash/scrub off the salt with warm water.  there's lots of examples and more thorough how-to's online.
