Hi mate,
Yes, was dreading cutting deep into rust and simethjng I wasn’t relishing doing to be honest. I took the rear trims off and removed the existing flaking and separating sound proofing. When I started I thought to myself, ‘wtf have I started here!!!’ I really didn’t envisage having to replace soundproofing at same time.
I’m pretty glad I did to be honest, it is worth while doing. Bought some silver Vibe stuff from eBay. I then used some Bilt Hamber Deox C quit thick layerings a fair few times and also agitated with small wire brushes before removing. Before treating, I resorted to using a cordless drill with wire brush attachment to get the last black bits of rust remnants off, so it was nearly all shiny metal ready for coating.
I then used Bilt Hamber Electrox galvanised paint (3 coats) that stuff is awesome! - I then waited and applied Bilt Hamber Dynax S-50 which is a waterproof wax coating and can be used as body undercoat. Pete Hamber the guy who’s company it is talked to me numerous times over the phone and was amazing! After I’d done this I put the seatbelt pre-tensioners & belt reeks back in (forgot to say) screwed new Hertz Dieci 6x9’s into the frame as recommended and wired them back in.
Got to do a bit of work on the trims before putting back in
