Need help or tips on car builds (putting the body on the chasis)

I have built several cars and i always have the same problem evrything goes great until it comes time to pit the body of the chasis. everytime i do it, it never fails, the body warps the chasis or just does other crazy stuff. so my point is this are there any tips or anything i could use when i get to this point? it is very frustrating. i am working on an amt '69 firebird now and so far it is great except that i dread the part that will be coming soon.

I have had the same problems in the past, most recently with an AMT kit. I just do alot of glueing and holding till the glue is dry. If an area needs the extra glue i just sand down whatever needs it and touch it up with paint.

AMT is infamous for this…Other kits have thier problems but Ive found this to be an AMT disease! Like Chris said…lots of glue holding and patience

You could also try to spot-weld the parts using CA and once that is set than finish of with the modeling glue.

Works for me on warped Vynil Kits. [:D]
