Hey guys... There is a few rock chips on my car and there are starting to rust.. Is there an easy way to fix this at home or it needs to be taken to a bodyshop? Thanks...

get matching touch up paint.
use utility knife blade tip to clean rust away, works perfect, just dont do quick moves, do not scratch paint around. especially well clean border between good paint and rust.
touch it up with paint, cover all chipped area, do not go over good paint. let it dry.
touch it up again, as many times as it need to fill up chipped area.you should feel small bump over surrounding paint when you need to stop touching up.let it dry for at least two days.use wet 2000 sand paper to smooth chipped area, do not apply to much pressure.
then use buffing compound and soft cloth to shine sanded area.

Get on this as quick as you can. I had a small ding in the front lip of my hood on my 95 camry and it blew up to about nickel sized in a few years, all rust.

I lightly sanded the area with 600 grit sandpaper (cut circles out and glued to the top of a pencil eraser)
used Napa rust eliminator liquid on a small artists paint brush from a craft store
used touch up primer, again with the small artist brush (2 coats)
then used real Toyota touch up paint, again with the small artists brush not the brush in the container, put several thin coats until I had the height correct.

That held for several more years and never rusted again.

Wow, I have been doing it wrong. I just touch that area with paint and call it a day. No wonder the paint just comes off again.
