Yes, you should wipe the frame with solvent after treating with Ospho. It is not necessary, but since appearance is an issue, I would wipe it down with laquer thinner or acetone.
Herculiner Prep Work?

Ospho site says Do It Best HW has them so I'm going to call around tomorrow. ACE was a strikeout and was not sure I wanted to order the Ospho until I spent another hour grinding away on rust tonight:headwally:

I had the wife call around earlier and gave up on Ospho locally. I did found oxalic acid at Sherwin Williams for deck treatments labeled wood bleach. If it does not work, I might order some Ospho online and delay things.

Find an auto body supply shop near you and ask for rust mort or a rust converter. You apply it over rust and it converts the rust to a coating. You DO NOT remove the rust just apply it over top of the rust and it chemically reverts it and coats the steel.

How sure are you that ospho and similar products are compatible with herculiner? I can think of a couple reasons why there could be a problem with adhesion and I doubt acetone will be enough to remove the residual ospho.

If you read the herculiner instructions, it's typically applied to a scuffed painted surface so I don't believe that's a concern as I'd rather reverse the rusting process and turn the rust to iron phosphate than leave the rust as is. Whole stand will be wiped down with acetone twice to ensure no residue remains.

Just thought I'd share in this thread that I got the Herculiner on. Here's what I just posted in my Build Thread:
Finally got the Herculiner in yesterday so did some last minute sanding last night, wiped down with oxalic acid, roughed up with orbital sander 40 grit sandpaper, wiped down with acetone twice, and one coat of Herculiner on! I ordered two kits and think I went through about half a gallon. I may go ahead and do three coats in the next 24 hours
Anyways, here's some pics of it I snapped with the phone....Ones I took with good camera were foggy as my lens fogged up as soon as I walked out due to how humid it is today!

Not sure how thick it will be but just finished off the second coat and it's definitely thick already. Herculiner recommends additional layers on steps/high traffic areas to increase thickness/strength and many say it helps to add 3-4 coats to equal what rhino liner or other bed liner sprays. I'll see in the morning when I have better light if another layer is really needed!

I'd be surprised if Ospho were something other than phosphoric acid. Phosphoric acid is pretty good for removing rust, though it will leave pits. If it were my stand I'd use phosphoric acid to remove rust, then wipe down with ro water, rag dry and paint with a rust converting primer. Follow the primer with the liner coat and spray a parafin wax thinned with varsol into the breather holes(rotate the stand to distribute the parafin).
If you do all that and it still rusts then somone is out to get you.

Yep. One of these days I'll learn to refresh my browser before posting.

After three coats I'd call it good. It's nice and thick and looks really good....I'll have to flip it later to coat the bottom rail three times but that'll be a small job.
After three coats (No light spots like previous pic):

i own a body shop in Miami, Fl., have been in business 30 yrs and if it were mine, i would wipe clean with a pre-cleaner, treat metal with ospho, and then after atleast 24 hrs, paint. The ospho will etch, prime, and nuetrulize the steel. Painting will lock in, and will keep the metal from rusting, even if it is scratched or chipped. Rust is a big problem here, and we r surrounded by salt water.
steel is a combination of iron and carbon mostly, is very porous, and the ospho doesn't need to be removed since it is converted into the metal. No sanding required either. If u want a perfect finish, then first prime with a 2k primer or whatever u got, then sand and finish with a catalyzed paint of ur choice.
