Hi Kendal.
Filling low spots depends on a few things. .................

This is a very brief description of prepping for paint. You want to use good
urethane products all catalyzed filler, not lacquer. You will need a
supplied air respirator however as isocyanates are bad. There are some iso
free primers on the market which might be worth a try.
Good luck,
John

John's description is a terrific summary of how to do it professionally.
But, my guess is if you are asking this question, you will not have access
to a positive pressure respirator and, hopefully, you will be frightened to
death by the implication that isocyanates will kill you.
Don't despair. Go to an autobody supply store, tell them what you want to
do, and buy the smallest amounts you need. As a general rule, you go from
"rough stuff to fine stuff" with fillers, just like with sandpaper. The
roughest fillers, if you are unfortunate enough to have to use one, have
metal or fiberglass "hair" in them (hence the term gorilla hair). Try
bringing the dent "up" enough that you don't need this. Beyond that, you
have the Bondo-type stuff (Evercoat is only one of several quality brands)
which is what you'll probably use, and a top layer of really smooth
"flowable" putty (3-M makes a nice one that comes in a big pastic tube). The
process is a lot like spackling a wall or "taping" drywall. There are a
couple of good websites out there with detailed "instructions for the dummy"
type pages out there (do a Google saearch). But the supply store may be
your best resource.
Good luck,
JohnD
