Frame treatment?

[51 CJ3]

Thanks all, it looks like I was overthinking it... worrying about the areas that cannot be cleaned (where the frame is boxed instead of open channel).

The only way to get in there is a dip. Sand blasters can get in there pretty well but you will not get into the tubular front cross member or up behind the boxed areas all the way. When dipping the drain holes have to be opened up on that tube in front to be sure everything gets in and out. On the areas that can not be gotten to with the sand blasters wands, I use Eastwoods Internal Frame rust converter https://www.eastwood.com/eastwood-in...z-aerosol.html followed by a paint fog.
