Rusty floor pans
Moderator: Moderators
I did the entire inside and underfloor using a heavy duty angle grinder with an even more heavy duty dished, twisted wire brush and that soon sorted out the weak spots (which thankfully, there were very few).
It ripped everything off and left bright bare metal, which I sprayed with two pack epoxy etch primer as fast as I possibly could.
You might find my website useful to take you through this sort of thing...though I need to do a bit of an update in all the excitement I'm a month behind

I would derust the floor (which ever way), treat rust ares with Dinitrol, hand brush complete floor pans in red oxide metal primer (Bonda prime good) and then final paint over the top. Cant really see the need for spraying if its not a full resto and the carpet will be over the top of it.
Dont use cavity wax or tar based paint on inside of the vehicle, use the cavity wax for inside sills, pillars and doors etc and underseal for underneath the vehicle. The smoother the paint on the inside, the better for dealing with any damp that might occur

With the dintrol wax stuff there's one that dries quite hard but still creeps I used that on any seams whether they were inside or not.
On my 71 RR after putting the chassis connectors in and painting the floor I tipped a full bottle on the whole floor and brushed it out, waited till it had gone a little solid then put the carpet back, paying particular attention to any seams.
Me personally I think with seams it don't matter how much paint you get on there it will crack eventually with body flex so at least on the seams get some dinitrol wax on em after the paint has dried
