I am fixing up a Meteor. The keylines around the inserts are bad & most inserts also have a colored band as part of the keyline, which I cannot touch up very well. I made a sheet of rings on transparent laser waterslide decal paper using a color laser copier. The black keyline is great but the yellow & tan bands are not opaque enough and would not cover anything underneath of a different color in the event of slight size difference/misalignment. Does anyone have suggestions on how to get the lighter colors to cover better?

The only solutions I see are:

a. paint the colored bands white before applying the decal
b use white backed decal paper, but cutting precise circles inside & outside the keyline is difficult

Your input is appreciated.

Thanks.
