The Herculiner product can be easily masked to keep areas clean – areas we wanted to paint later -- and it covers a multitude of issues, sheet metal patches and welds when it dries.  It’s not an original OEM item for a period-correct resto, but for this application, the stuff looks great.

After recovering from the fumes of the undercoating, we off-loaded the Cuda from the rotisserie with the help of the lift at Mercenary Off Road and installed new spring perches and leaf springs purchased from Firm Feel. 
First the spring perches were bolted onto the A-body chassis and then we hung the springs.
