What apps are best? I want to tint back windows, plasti dip grill black and thinking of dark alloys but want to try it out with photo editing first but have tried loads of apps and they don't do what I want :-/

Do you have access to a computer? A great free image editing program is called Gimp: http://www.gimp.org

Il get in the other halfs computer tomorrow! He is wanting to do the grill on his fabia vrs as well so could have a play about with pics of his car as well. Cheers :-) have tried so many apps on the iPhone but useless!

I have a colour changing app on my iPad I use. It's free as well. Admittedly you can't get textures, but to mess about with colour ideas is great.

It's called color effects

Here's just a couple of chops I've done with it

Oh yea that's pretty good compared to some I've tried!
