Still struggling with the blue? Just get some Dykem Hi-Spot Blue and get on with life. It works great, cheap, and available everywhere. Currently $13 from Amazon.
I think the mess is exaggerated, it's really not that bad. The stains on your hands will be gone after a day or so. It will stain pink granite, but the stain does fade over time. The only big problem I've had is that it will stain painted surfaces, I haven't found a solvent that removes the blue without damaging the paint. Scrape before painting.I really hate the idea of using Dykem and putting up with the mess.
