[Shop-talk] Trailer clean-up and paint

[Bob Spidell]

I've used Permatex 'Rust Treatment' a couple times and had good results:

*As an experiment, I treated a wheelbarrow with surface rust with it (no 
sanding or wire-brushing).  It goes on clear then turns the rusty parts 
black, which indicates to me there is actual chemical conversion.  I 
then painted it with the usual enamel rattle-can paint. After 20 years 
or so outside the paint is faded but there is no rust.  I'm a believer.

Recently, I 'restored' my late father's fire hydrant--someone gave it to 
him, I think because he was restoring a fire engine--which had several 
coats of paint and considerable rust. I spent an hour or so with a wire 
wheel on a 4.5" grinder to get it down to (mostly) bare metal, but with 
some rust remaining.  I painted it with RustOleum rust converter paint 
which came out like black paint but was about half the cost of the 
Permatex; it took more paint to cover it.  My guess is it's just black 
paint with some rust treatment additives, but it's just a guess.
