I just started on this side tonight. This was one of the weak points in my 280... the frame rail itself was not rotted.. but the seam above it was.. Used por15 powermesh fabric combined with the paint itself to start treating and reinforcing the area... So far I am VERY happy with these results.
50 percent of the front chassis was stripped to bare metal and treated. In areas where the original undercoat was I left... I only attacked the upper and rusted areas.
I have a 77 280Z that is virtually bone stock... no ignition mods or anything of that nature. I run a blaster 2 and have never had any problems.
They are readily available at Autozone and are 35-40 dollars.
