I have a D40 STX 550 Spanish built, never off the bitumen.
Used a borescope ($200 from TradeTools) and found I have rust establishing inside the chassis rails. The exterior paint of the rails is fine with no rust at all.
A rust guy said don't use fishoil or lanotec as dust sticks to it making it impossible to manage later. Also said his own propriety underbody products are too thick to spray inside.
Any thoughts?
