I've  just found a small spot of surface rust by the front step on the
driver
side. I was going to sand it off and spray it with some zinc  chromate for
the time being, just to stop it from spreading, and then worry  about the
actual painting later.
The problem is that I think it's too  cold to use the primer, and I don't
have a garage to do this in. It's about  30 degrees outside, and the product
calls for 70 for best  results.

Is there something else I can do in the meantime to slow down  the process
until it gets warmer? I was thinking of putting some sort of  oil on it, or
maybe spraying it with spray on wax to keep oxygen from  getting to it.

If you have any suggestions, please let me  know.
Thanks!

scrape / sand area then heat it w/ a hairdryer then use some "extend" or
other brand of rust converter on it..paint it on w/ a q-tip.  heat it w/  the
hairdryer till it dries black. this will hold the rust at bay till spring
or  when u can fix it in a heated garage.
