I just started a Tamiya M48 "Patton" model and was hoping to put it into a Vietnam diorama. The problem is that I have no idea how to weather the tank so it looks worn and beat up. On previous models I did, I usually side stepped the weathering process but on this tank, weathering is a must. So if any one has any advice or tips on how to make this tank look like its been thru hell, that would be extremely helpfull. I guess I should mention I'm on a limited budget also... Thanks!
