I rinsed the frame out with a hose, now I want to dump used motor oil down the open end of the frame. Does this sound like a good idea? What have you done, if anything.

 

yes thats the way ive read on here you do this but i also add if you like get some spray fome the great stuff and spray that inside the frame as well it should seal up everything nice in there as well

 

Took you long enough. Do you mean expanding foam? I don't like the idea of sealing the frame, because if moisture gets in (and it will) it can't easily escape.

Anyone think of a way to mist the oil in there?

 

a spray bottle? and if you get the watter proof stuff it should hold out all the water and everything else lol and sorry it took so long buddy

 

Get an undercoating spray wand.

 

I use a "shutz gun" and a small paint brush to do my frame ..
2 wands .. first is a rotating 360* "V" notch . Second is a 90* rotating .



I'm VERY happy with the way it came out ..

 

damn you! That looks so damn purdy.

 

I'm thinking more body-still-on-frame type rust prevention.

 

I use a sprayer like for lawn care. The ones you pump to get pressure and it has a "wand". We mix oil and a little kerosene to thin it out. Park on a good incline and go to town.

 

if only i could take my body off and do it that way man it would make things so much easier!!

 

I guess you just park over a bunch of news paper to collect the drips that come out the frame, then burn them afterwards.

 

I just did POR 15 on my frame on the outside. I am planning on using a pump sprayer like you can get at LOWES in the garden section for $20 and stick the wand in the holes of the frame and spray boiled linseed oil. Farmers have been using it to rust proof metal, and protect wood for centuries. Also if you get it on the ground it is no big deal. Plus it gums up like glue and sticks real good. It would be a PITA to get it out though. You might spray some phosphoric acit in there first to get rid of as much rust as possible. Thats the stuff that comes with the POR 15 frame protection kit. You probably could get it cheaper at a farm store though, you can get the linseed oil there too. The nich thing about this is no mess. Do it at home, then the next day go to the carwash and wash it off the outside of the frame so it doesnt look bad. You will have to presoak with the degreeser. Good luck.
I guess if you want to use used motor oil that works to, just not as well IMOP, plus you will be dripping oil on your driveway for a month.

 

Boiled linseed oil eh? I'll have to look into that.

(wonder if bacon fat works)

Anyone know where I can get phosphoric acid for cheap? The Rust Mort costs too much to spray it.

 

Try a boat yard.

 

There is something called naval gel (don't search nave gel). Which looks to be perfect. Its not really spray-able though, and its equally expensive.

I called a boating store, they didn't carry any phosphoric acid or navel gel, but said lanolin oil is commonly used to protect motors against rust and barnacles.

 

bacon grease might work if you dont mind the raccoons...

naval jelly isnt going to work on the inside of the frame. its not nearly as impressive a product as it sounds.

phosphoric acid is commercially available as a rust converter.

Heres a brand that we've used on some of the ships i've worked on

basically through a chemical reaction it turns iron oxide (rust) to iron phosphate (hard black stuff). You're supposed to chip off all the loose rust, and It doesn't work on thick rust, or you'll just be back repainting it soon after. You spray it on, and let it dry. The rust will all turn hard and black. It leaves behind a nice white powder, which you wirebrush off, and then you can prime and paint it.

 

I'm going to use Fluid Film inside my frame. I'll post up some pics once I'm done. I just finished coating the back half of the frame with POR - 15.

 

I used a spray can of Amsoil metal protectant on the inside when I restored my frame. http://www.amsoil.com/storefront/amh.aspx Seems to have done the trick for $10. Super high pressure spray too. Painted Zero Rust on the outside and it looks great. (all done with cab on.)

 

I put about two gallons into my frame rails the other day. Just let the eccess run out. I just used a diff syringe. Looks like a grease gun but is used like a syringe. use it to fill diffs etc. I didn't rinse my frame out first though. Probably should have. Acually you dont want to seal up your frame, because if any water or moisture gets in it cant get out and it will rust for sure. I made that mistake already.

 

2 words for rust proofing...fluid film
