The first thing to do was to rub down the edge of the red paint panels as the edge was raised where it had been masked off. I applied some fine lining tape wither side of the paint edge then rubbed down gently with wet and dry used wet until the edge was removed.
I used 3M fine lining tape, 1/4" and 1/8" in the blue and 1/16" from their multi fine line striping tape. This multi line tape is built up with a 1/4" piece of tape on each side and then 8 1/16 strips between. You can separate it to make it narrower to go round curves and then just pull out one of the 1/16" strips for the gold line mask.
I set out the location of the 1/4" wide gold line with a strip of tape which covered the joint between the red panels and the black of the tank. This tape was later removed in order to paint the gold line when each side of it had been masked off with more tape.
I settled on a 1/8" gap between the 1/4" gold line and the inner 1/16" gold line as a wider gap would have meant the 1/16" line was too close to, or under, the instrument panel. This 1/8" gap was set out with lining tape and was then bordered with 4 strips of the 1/16" multi lining tape, the inner strip being removed for the 1/16" gold line
It was then a matter of applying the gold paint. I used 1 shot signwriting paint applied with a squirrel hair dagger type pinstriping brush putting just enough paint to cover the base. It took two coats and they were applied with only a couple of minutes between as the paint skinned over pretty quick. I only left it for about 15 minutes (it was by now just touch dry) before carefully removing the masking tape, the idea being to allow the still soft paint to spread a little at the edges in order to reduce the hard raised edge you get next to the masking tape. It is important to pull the tape off by folding it back on itself and keeping it at as low an angle as possible to the tank surface whilst also pulling off at a 45 degree angle to the line of the stripe. By doing this the tape 'cuts' through the paint film and does not pull the paint up.
