From your pictures, I think that you did a great job of painting & mounting the body. Especially a HPI body on an Associated chassis.
Really is the ONE thing about R/C that I hate, painting and mounting bodies.
We usually race at least 4 cars at a race and I'm the mechanic for all of them. My son is 7 yrs old (speed racer) and my stepson is 24? (chim-chim) and not very mechanicly inclined. So I get stuck with all of the dirty work.
