Ideas for tank underside

Im in the process of prepping my tank for painting and I found that stripping paint from the underside left it not nearly as clean as the topside. I cant get into all the crevices to make it all spotless. So I got to thinking... Why dont I just coat the underside with aerosol bed liner? What do you guys think? Will I create any clearance issues? Will the bedliner stick to the metal if its no perfectly clean?

I don't know ANYTHING about bed liner.
 
I've used rubberized undercoating rock guard. Likely not as thick as bed liner and makes a nice tough coating that is paintable.
 
I'd just paint it with whatever paint you use on the surface.
Clean it with soap and water, scuff it with a green scotch brite and move on.

ooo undercoating is also a good idea...

Here are my two best options so far;

This is what I was originally going to do... But Im concerned about corrosion, If I paint it normally and it flakes then Ill have bare metal.

Would the tank cushions then go on after the undercoat?

I was concerned that the liner/undercoat would reduce the clearance for the cushions, I dont actually know how thick it is, anyone have any idea if this would be an issue?
 
I'd prep it just like the top. Strip - sand (or wire wheel) - prime - paint. If there is still rust in the small crevices then I'd get some POR-15 paint and seal off the rust. No reason to resort to some thick coating, it's unlikely to seal any better than paint anyway. Thicker is not necessarily better.

There isnt really much rust, actually, on the underside, just gunk from the stripping process. Its hard to properly clean it and as a result I worry that the paint will not stick. I assume that undercoating or liner WILL stick, its not the thickness that is protecting it, its just that it wont fall off!

Slather on a second coat of paint stripper and give it enough time to work. Hit the edges with a small wire brush. Problem solved.

I plan on this, but whatever paint the PO put on doesnt work all that well with the stripper. Its not that the stripper doesnt take it off, it just kindof mixes with it and makes a sludge of stripper/paint. That dries and im left with black goop dried onto the surface. I think I may try using some acetone to see if that will take off the goop.
 
Don't use spray on truck bedliner unless you like excessive weight and plan on not ever removing it--ask me how I know.:o
 
Herculiner, its roll on and get it from auto parts for around $15 bucks.

Used in lots of offroad apps specifically lower panels on doors and to protect areas from rock chips that were protected by mudflaps and you control the thickness.

You also have lots of options from 3M.
