I have found a number of dings, tiny dents (in odd places), scratches,
and missing undercarriage pieces on my 98 M3.  I have already learned
from this group that this particular car (4 door automatic) is not very
worthy of my time but I still like it.

I have the E36 manual and can do just about anything I need to now.
What I do not know how to do it fix the dings and chips myself.  I fill
and send and fill and sand but they never seem to go away.
Recommendations?  As far as the little dents - they are in places that
I am not sure how to get to.  In the front quarterpanel, on top, next
to the hood.  Like something fell on the car?!  Is there a way I can
fix these or do I need a professional?

Thanks for any help, JM

PS: The car is yellow so matching paint is a bear.
PPS: Did they use clearcoat back in 98?
