Just buy the brown stuff at your local hardware store and volia you got a bottle of mud.
heres how u do it:
1: Shake it up and take off cape ( bet ya didnt know that! #:-) jk )
2: Squeze the bottle onto the model
3: put out in sun till completey dry ( it tends to dry on the outer layers why the iner core is wet)
4: Apply a second or third coat and dont forget to pull the bottle away while your squezzing to give it the drippy mud look
5: Dry brush a brown paint onto the model and your done!
I used the wood glue on these models here :
British Infantry Tank Matilda and theT-72
tell me how it works or if you have any thing to add on
