How am i supposed to 'rinse with water' (POR15) once pan is welded in???

POR says you are to rinse with water after Marine Clean and Metal Ready before applying the POR paint. how is this done when the pan is in the car???

would a sponge and towel be adequate?

I'm assuming you mean the floor pan. If so try the following:
This may sound unorthodox to some but this is how I would do it:

1. jack up the rear end about 3-4 inches so the water collects at the front

2. flush thoroughly with a fresh water supply i.e. (a garden hose)

3. remove water from footwells with a wet vac

4. towel dry the rest of the moisture, then let air dry for 24-76 hours before painting

Best of luck

sorry, meant suspension pan. my concern is water getting in the longitudinals.

i'm thinking i'll have to prep the replacement pan before welding it in. i imagine i'd have to prep, weld in and paint all in the same day to avoid rust forming though.

Yes, a damp towel/rag/sponge will work. Best to wipe 3X and then dry. This is to rinse the residual salts off so the paint sticks to the newly etched metal.

I struggled with the same issue when I had to do the interior floor and seat pans. I ended up initially using a shop vac and towels then I drilled a couple of strategically placed drainage holes.

I left the holes in when i POR'ed and then plugged them with body plugs and silicone. I shot the holes from the outside with rockerguard or undercoater to add some extra insurance.
