>Ray....I agree with the other posts, but I take just a little more time
and end up with a surface that is ready to sand flat, prime and paint in
the spring:
>I take the car in a warm dry garage, clean it up, and use the Dremel to
surgically remove the rust down to bare metal. It takes about ten minutes.
This creates a depression in the surface. Then I put a thin film of
phosphoric acid on the bare metal and let it dry. A hairdryer speeds this
up. There goes another ten minutes. Then I mix about twice as much epoxy as
I think I'll need, and I mix it two or three times as long as the
directions say, using left-over popsicle sticks. The trick is to get
exactly 50-50 amounts of resin and hardener, and mix it down to a molecular
level. Then when it sets up, it is hard as steel and glossy. Mixing takes
about 5 minutes.
>Then I dab the prepared spot with enough of the epoxy mix to bring the
surface up level with the surrounding surfaces....usually use a small
disposable watercolor brush, a wooden toothpick, and some paper towels for
the hands and to wipe off any accidental/excess dabbing. It sets up
overnight and is able to take outside the next day. And you can wait until
summer to smooth it off, prime it, and paint it. I keep any extra mixed
epoxy on a card, near the actual repair, and test the epoxy on the card to
see how the repair is actually setting up.
>I use a product call SUPERMEND, sold at local ACE hardware store. Yellow
and white box with red lettering. About $5-7 I think. One box lasts 6
months around my house and we fix anything that breaks....cars, boats,
chairs, other toys, drawers, broken knobs, etc.  SUPERMEND is able to set
up under water, and is waterproof when hardened. Don't use an epoxy that
isn't waterproof. It will soften and have to be replaced.
>I used this to fix about 25 rust spots and stone chips on my 86 4KQ this
fall, and it went very well. Whole process takes about half an hour to 45
minutes, and you are at least half way done with a permanent repair that
can be delayed indefinitely....years if necessary.
