The blue dots are in the finish, not sure what they are as with out the "Flash" of a camera they are not noticeable, may be an air bubble that flares with the flash, as to ease of application, I think it is easier, three coats of the sanding sealer dries to touch in 3 to 5 min sand to mm3200 three coats of the top coat dries to touch in 3 to 5 min, cure over night and sand to 1200 then buff, watch out for heat, will burn quick or melt. what I like is no CA Fumes. I still do the CA as it is faster for finishing, but will "take me longer" to finish a pen I end up doing a lot of sanding with CA finish, for some reason I get a "popcorn" finish when I do a CA finish, there is a good lower finish but end up with little white balls all over the surface of the CA.
