Rustkiller on galv?

muzz67, Sep 21, 5:05pm
Galv trailer has rusty patches where motorbikes have dropped petrol, (weird)
is it ok to use the acidic rustkiller on it? Have used it on non-galv with good results.
Cheers.

The rust is there because the zinc galvanising has been scraped off.

If you use a rust killer, then paint it with a zinc paint ASAP to stop it rusting again (as fast)
