Under Motorcycle WIP I see a lot of bike's frame parts such as swingarms filled with putty to be more realistic. My experience with gray putty bought at USA hobby shops is that after curing it cracks, deforms and after sanding, I have to fill again the cracks, sand and do this few times until I get somewhat of a smooth surface. Too much waisted time for not a nice smooth surface for my liking. I know I'm missing on something that is out there. Instead I see some of you all in here with swingarms filled with a material that looks like a poly with clean lines and an ultra smooth surface. I was wondering if there is a product out there that could make my life easier that will look good too without lots of work. Thanks in anticipation of anyone's reply!
