oh yeah babe, they have whatever you need at walmart boys. the auto section definetly has the finer grit of papers. i also love those little plastic containers over in the crafts section. they are all connected and i think they come 24 to a pack for about a buck. they have a lid that stays attached to the container and i just cut them apart with my sprue cutters and mix paint or whatever else in these handy little jewels. they are about the size of an omni 5000 paint cup. there cheap enough to just chunk em when you get through with them, or you can clean them and use them again.
i swing by the electronics section and pick up a pack of those alcohol wipes for my computer that claim to put a negative charge on the plastic so dust is less likely to come to rest on the wiped area and leaves no residue to boot. heck, my small town walmart even carries a testors airbrush set! i couldnt believe it when i saw it.
the above is just a few of the items i use from walmart. however, i could go on and on.
later.
