Blocking and bodywork

No experience with that brand. I did use a lot of paper from Orielly's (MasterPro brand) with good results.
3M stuff is almost always the best, but also very expensive for a hobbyist.

Thanks again! I'm gonna order the 36, 80, 180 and 320. I'm also gonna get the 3M platinum body filler. I am SPI epoxy and 2K High Build. Not sure on paint yet, the painter at my work suggested Martin Senor from Napa.
