i have used the Friskit paper and i dont use it any more especially on HOK paints, Scott turned me on to Automask paper and it is more HOK friendly inter coat clear is a clear base coat and it eats into that just like base coat, you will always get tape marks in HOK paints but the friskit really did a number on the job i used it on, but i was able to save it. I would use the auto mask or just tape the iron cross with masking tape and fine line tape. Artool makes a Diamond plate free hand shield i dont have it yet but i would check it out if i were you it would save a lot of masking time.
