How long to paint your chassis?

[NEroadster]

I have used metal ready to keep the rust at bay during the build and also once the chassis was finished. This worked brilliantly at preventing further rust and also removing existing rust. It also acts as an etch primer. Finally I am planning to use the POR 15 range I have already used it on the wishbones and front uprights and am very pleased with the result. All paint available from Frost auto restorations
