Yeah, buddy!! It really helped out a lot, I think. I was a bit worried that they would break, as per Stephen's warning, but luckily they held together, and it was fine.
I just got the MG's assembled and painted, so now I'll get after the detailing, and then I'm going to post them.
I'm pretty stoked about them--they're my firsts and they may not be perfect, but I'm a bit proud!
