Tank disaster...and the biggun!

So, I've been wanting to increase the weathering/dirt on my tanks...so I attacked them with the Army Painter dip and a brush.  Big mistake.  The dip had started to thicken a bit since I bought it, meaning I've been left with some streaking visible after "washing" the tanks heavily.

I've added some insignia and increased the foam stippling. Overall I'm a little miffed, but they're still serviceable.  I attacked some areas with mineral spirits in the hope of saving them, but I failed miserably.

I have added to the collection some bits magnetized to give me a Vindicator stand-in for my Chaos force.
