Last night I took off Grimlocks arms, and Sludges legs, due to looseness. What is the best way to make those limbs tight once more? Do I put a layer of paint to make it tighter, or is there a more effective method? Please help me out, I've been able to fix quite a few G1s with a screwdriver, but these joints are more loose due to wear and tear I believe. I will also be doing the same to Slags legs, once I get a good method. (didnt want too many screws laying around) Thanks alot!!!!!
