Need to do a bit of work to stop mr rust, after removing old and flaking underseal, whats the best treatment (I am thinking of after primer/rust inhibitor) ie stone chip or similar! ;D
I have had Dinitrol sprayed all over Major, underneath, wheelarches, chassis rails, cavities, the whole lot including inside doors etc - he was gently scraped back to paint, epoxy etch primed and then Dinitrol'd
I use epoxy mastic... comes in at around £140 for 5 litres... not cheap, but really good www.rust.co.uk I'm with mork on the dinitrol, but I use the cavity wax
