Firewall Painting w/ the motor still in?

Any of you guys ever paint your firewall without taking out the motor? Thinking about trying it in my 54 Chevy but I'm not sure how its going to turn out. Any advice or pics would be very helpfull. Thanks

 

someone on the HAMB recommended using tin foil for masking cables and wires... try it.

 

Did it on mine,turned out so-so. hardest part is trying to buff out by hand.

 

garbadge bags and packing tape

 

make sure to clean it real good with a degreaser. i used liquid sand paper that you get from a hardware store. tin foil works good where it is hard to tape off
