Slowing rust progression

Weed sprayer should work fine. You just might have to experiment to get the mixture right, Probably as much oil as possible with just enough kerosene to thin it enough to spray.

Used the rust converter (Wurth) on a chassis a few months ago. A little goes a long way - it is thin & goes on with a paint brush, spreads out easily & I used about 100ml on a truck chassis.

Might be a good idea to use rust converter on the rusty bits first, let it react & cure then spray the oily spoodge over the top. Probably last forever unless it's a Fiat.
