Cleaning Inside "frame"

[dfreeman616]

i've been cleaning up my truck and looking at doing some rust repair, and found a lot of junk built up in side the frame. i've been able to get some cleaned out through the drain holes, but there's 25 years of salt, sand, and other dirt built up in there. some of it i've been able to rinse out, but water isn't doing it very fast. anyone find something that works well?

no one has any suggestions?

I used a 3M wand and attached it to my UPOL Raptor gun to apply the por15 product line to the inside of my frame. The frame is made of several channel so be sure to go in and out of EVERY opening in the frame. My 92 build page has a few more details on what I did.
