It looks absolutely fantastic so far I would really like to have a steering front end like that could you post more detail pictures as you continue on with that
Do the later re-issues of the AMT 70 impala have the Axle thru the Engine or has that been revised? If it has'nt what would be a good donor chassis for this kit?
Sounds like you may have had some oil possibly from your fingers on the painted surface after letting the paint dry wet sand the surface down some and try some grease and wax removerto prep it for paint
