You're welcome Bill.
I normally paint the tape with the interior colour first, so that it 'looks right' through the transparent part. When dry, the exterior colour is then painted. The interior colour also acts as a primer, making it easier for the external colour to 'key', and I rarely need a second coat, depending on colour of course.
However, it's better to give a second coat, rather than 'rough up' the tape. Sanding it can cause it to split once removed from the glass.
Remember to cut the lengths longer than required, to allow ease of placement, then trim-off excess once in place and rubbed down.
