Kerry's 330 GT Restoration

Coil and Ballast Resistor Painting

As a result of the coil dying on the way home from the Monterey trip, I decided to pull the distributors and have them rebuilt. 

The coils were from a 308 and the ballast resistors were missing most of their paint.  I couldn't very well put them back on without correcting this.

Finding the correct paint colors was a problem.  Tom Yang couldn't remember what color he used.  Lowell Brown used a Rust-oleum burgundy on his that didn't look right to me.  For the ballast resistors, I used a Rust-oleum custom tint color of Brick Red (from Home Depot).  I tried several different spray cans of various red shades, but nothing matched the paint color where the brackets had been removed for the coils.  I ended up going to an auto body paint shop and in their big book of DuPont paint chips found RS632 enamel that looked correct.  I hate to say what the quart of paint cost since you also have to buy hardener and reducer to match.
 

The new coil stickers came from Parker Hall.  Parker also has a rubber stamp kit for the resistors, but it was pretty pricey just to do two resistors.  So for the yellow lettering on top of the ballast resistors, I made a Word document that matched the old lettering.  I found a place that makes custom rubber stamps from a printed sample.  I brushed some yellow model paint onto some scrap metal and then used it like a stamp pad to get the paint onto the rubber stamp.
 

Original Painted and stamped

Since I was having the latest batch of oil filter wrenches cadmium plated, I threw the coil brackets in with them along with a couple of other items.  Here's everything back together ready to attach to the distributors.
