I see in the instructions and from several posts here that people are using packing tape for masking before applying thickened epoxy. I also have seen images of people's projects where it appears that they are using painter's masking tape.
My experience on other plywood (i.e., not Okume) is that packing tape can peel plywood grains (i.e., raising wood fibers from the surface and effectively gouging the wood). Also I have seen that painter's masking tape can allow bleeding on plywood because of the uneveness of the surface and also the lessened adhesiveness of that tape.
Can I hear from those with experience of masking off joints before sealing with thickened expoxy as to your satisfaction with the method you chose? Should I not worry and use either the little red packing tape dispenser or the roll of blue painter's masking tape?
I appreciate your comments. In fair disclosure I must admit that I have not been able to unpack and inspect my plywood because I bought while CLS had the Oct 31 sale, yet my garage is still overrun from a kitchem remodel that is in progress (and behind schedule - still more experience contributing to my "handle" on these threads).
