100 mile/hr Tape rescue

[TerryWighs]

After just finishing the dreaded nightmare of bondo/fiberglass tips on the empennage, I thought I would share my discovered/foundness for 100 mile/hr tape (duct-tape...) This may be nothing new for those with far more experience than myself, but I decided to mask with duct-tape before spreading the superfil/bondo...
I was pleased to find that the tape holds up to a fair amount of sanding, and when the tape is removed a very nice clean line is left. Acetone then removes any underlying tape glue....
I also came to the conclusion that I am forever grateful in my decision to build an all aluminum aircraft with minimal fiberglass labor...

Every time I had to fill and area I just layed on layers if fiberglass then sanded to the right contour. In 2.5 years of flight ops I haven't had any edge cracks develop. The tape mask sounds good.

Terry,
Does this mean you sanded through (or nearly through) the tape?

[TerryWighs]

Not entirely through the tape...just enough on the edge to feather the superfil...
