Ok, if you want to go with the LA color dip you can get close with this blend:

Take 1qt of Performance ACK-200 (920516) Black and add ½ pt of Performance DX-10-FLT flattener, I believe that’s 4:1.

Of course the best match will be matching a sample of your own surviving dip coat, it's harder to match than most might believe, mine came out really close to my original.
