Thanks Guys! I actually took a decent pic of the back of my trailer this morning that sorta shows what im going for....only not the black grime, more of a sandy look if that makes sense
JC- i use highly diluted oil paints. Its sort of the same idea as the acrylic paints, but it takes forever to dry so you have plenty of message time! JT- i knew i would get your approval on the color lol. Not sure about the weatheri g being geographical, ive seen this type of thing before...only not so heavy. I think ive used too much and ill try to tone it down some. Thanks for the encouragement fellas!
