Sorry, I was out for a while.. I used a Sharpie permanent marker extra fine black. Right on with the rubber windshield washer hose 1/4 ''. I had some small sharp pointed sissors I slid into the hose and split it . I glued it on with white canopy glue. I have not sprayed any clear enamel or sealer over the panel lines.
Thanks,
1/4" drip line tubing works good too. Home Depot where the sprinkler stuff is.
Regards
Michael
