I have read several post saying that boiled linseed oil can be used to coat the inside of my cj frame. Most of the posters were doing a frame off resto which im probably not going to do. My questions are:
Can I spray the linseed oil into the frame with out doing a frame off and if so are there any special precautions to take?
Lowes / Home Depot has it. It's used to rust proof metal tables, vices, etc. Curiously, it's also used to treat the threads on spokes prior to bicycle wheel building because it's lubricating until it hardens...
Linseed oil is the base to linoleum. It's a great sealant. However, I don't know how long it would last, or how well it would stand up to the elements. Even inside your frame it would still get hot and wet sometimes. If you're going to spray it in anyway, why don't you just spray in POR-15? It's made for that purpose, and it will last.
I used it inside my frame, but I did do a bare frame restoration. In your case, you should try to get as much loose debris out of your frame as you can. There is typically a lot of stuff accumulated inside jeep frames. If you don't get this crap out, the linseed oil won't actually coat the frame, it'll just lie on top of all the loose stuff.
Also, it doesn't really "spray", at least not with a garden type sprayer. It just "pees" out. Getting this oil to completely coat the inside of the frame, is VERY challenging. You wouldn't believe what I went through.
The point is, no matter what you decide to use, as much of the loose stuff as possible has to be removed.
Waxoyl is very well known in the Land Rover community. the Eastwood antirust i used it on my own Land Rover (to cheap to buy Waxoyl) this worked great.
For the areas that there is no access the you have to drill holes and the kit comes with plugs.
I would look at this and get the gun with it. You can get all areas of the inside of the frame.
POR 15 is great for the outside of the frame, but for the inside the stuff above is what your looking for.
On a serious note, I'm a POR15 and metal ready advocate too
