Protecting new parts from rust

Blink · 1st August 2019, 08:40

I'm putting new parts on the underside of my car and I'm looking for advice/ideas on how to protect & rustproof them before they're bolted back on.

New parts include rear subframe, trailing arms, upper & lower arms, brake backplates, discs, hubs, rollbar, etc.

The factory paint on these items isn't the best so I don't know whether to just put more paint on top of the existing paint (after keying it) and then apply wax over the top of that.

Or ...

Strip all the existing paint off (sandblast?) and repaint with primer and top coats, then apply wax on top. This is obviously a very expensive route to take.

Any suggestions?
