Well i think frenzy rumble has mentioned this several times about using sign material. so i give credit to him for this. anyways if you are going to use signs like this you need to know the diff between styrene signs and vinyl ones vinyl kinda sucks to glue. some one more inept than me can explain the diff please. but anyways the reason i bring up this thread is because if you need thin styrene stop paying out the nose at the hobby shop the smallest sign cost 69 cents while the largest one cost 1.79 @ walmart. i use allot of thin styrene and got sick of paying so much for it. also you can find styrene for free there is allot of small signs made from styrene so sometimes you can find it just laying on the ground blowing in the breeze no seriously.
