Hood Bulge....How to Fix?
the center (eyeball it), put some kind of anvil(s) where
they will do some good - like white wood blocks - and
use something soft like a dead-blow mallet to bump it
back if it's a large hump. For small, you want to put
some blue masking tape over it, get an appropriate
hard anvil (body dolly) just bigger than the lump, and
slap it flat with a bodywork hammer. Harbor Freight
has good-enough cheap tools. If you're slow and
careful you can bump it flat without ruining paint.
