Nice. Headed to the garage now

Thanks very much for this detailed lesson. I'm relatively new to skiing and this was super helpful in preparing for my first ptex job. As a former NASA optical tech, i.e. professional prep and bond monkey, I gotta give you props on your surface prep and bonding technique, especially the bit where you mentioned the importance of a "homogeneous" (laminar) flow of bonding material. That said, here are a couple couple minor, generic notes from a nerd: 1) You never want a surface to be overly smooth before bonding, as surface roughness is critical for a maximum strength bond. Definitely agree with smoothing out those rough notches with the blade, but for others/generally speaking, resist the urge to polish any surface totally smooth before bonding to it. 2) In this case where you want to remove relatively large chunks of material (wax and ski base), I'd probably brush and/or vacuum the area before going to a cleaning solvent. Solvent should be reserved for removing microscopic material. 3) I've never used this Total Boat stuff, but I would always recommend isopropyl alcohol over acetone. Even if you do want to use acetone, it is best to save it as a very last prep step because it is not as effective at removing relatively large particles and dries much faster than alcohol, and hence tends to leave behind a residue that can actually worsen surface contamination. Isopropyl alcohol dries slower, is a little less caustic on the lungs, and is more effective at removing the scale of particles likely to be generated after a sanding or razor blade job. Also, alcohol won't melt plastic if you accidentally spill some (speaking from very expensive work-related experience here...). Cheers and thanks for the helpful videos! The personal touch with the kid in the boat is a great example of what makes KZread the world's greatest classroom.
