New tools!  After squeezing out the 3M Windshield Urethane with a $5 Chinese caulking gun, I realized that wasn't going to work.  I ordered a Cox 41004-2T Ascot, designed for high-viscosity caulking.  Also, a Mayhew bronze punch and Ajax air hammer punch.

I started sanding the firewall, and realized it needed more work.

More mud; more sanding.

Against my better judgement, I sprayed some Upol high build primer because I was having trouble seeing the shape.  This shit sucks. 

Ready for another round of real primer.
