I use only 3M auto tape from the auto paint supply shop. Not Autozone, O'Reilly's, etc., but the store that supplies paint to the local body shops. Our store can order any color, size, or multi-stripe I ask for. It's not cheap, but the quality is second to none. I seal it in a plastic bag and it lasts a long time. R/C and other "cheaper" types of tape is a complete disaster for our level of desired quality. I always spray some form of 2 part clear over it and never had a problem.

Our local English Paint store which has about every automotive finishing thing you could want does not carry any striping tape.  They tried to sell me the 1/8" blue stuff that we use for masking.  Really weird.  That 3M stuff is all over the Web though.

Just out of curiosity:

I am not suggesting it but has any body tried Nail Striping Tape that they use in the beauty salons?  It is thin, cheap, comes in way too many colors.  Plus it is designed to be clear coated.  Since I am electric, the only chance of fuel getting on it is if I set the plane down in a pipe puddle on the circle.
