Yes, it is your money...
$7 bucks per bottle, $20 bucks per quart, $70 bucks per gallon for the liquid stuff recommended on this thread...but from your pictures...the rot is underneath the existing protective coating...so you'll have to do more than just these liquid band-aids...as it will continue to rot from underneath that coating
Until you remove that coating down to bare metal. Think of that rot as cancer and will continue to rot until it is removed and the root cause ID'd...am guessing road salts, which is a galvanic action...maybe nicked it during setup/take-down
Note my sig and how long I keep my vehicles. They do rust and take care if it before getting out of hand. That is my savings on vehicles...keep them until either won't/can't fix them anymore
If me and wanting to NOT get a replacement...drive it to the local welding shop. Have them sandblast it down to bare metal (in my area, about $50 bucks for the whole receiver...but have my own sandblaster, so kinda sorta a freebie) and then either have them repaint or a DIY.
Since still on the vehicle, no powder coating (my preference for this app), suggest Aquapon, my fav paint-on metal coating (next is zinc rich with actual metal particles)...or you can shop local hardware stores for on sale spray can paint...which won't be nearly as good as Aquapon or zinc rich

Check out how the cost of a brand new, traditional design receiver costs...best of them runs $150-$200 bucks plus about an hour's labor to remove/install
Vs all of the work messing around with your old one...that will have a poorer protective coating than most of the new powder coated receivers
If I was to buy something new every time something was a little older I would be broke.
