I noticed this guy's lay-up order is the opposite of what Paris described in the original post: apply the 2" tape first, then the 1 1/2" then the 1". I'm going to be doing this myself in the spring.
The advantage of putting successively wider pieces of tape over one another is that when you go to fair in the edges of the tape, you only have to sand one edge. If you stack the glass up like a pyramid, (successively narrower pieces on top of one another), then you have to fair in the edge of each piece of tape, so more sanding.
Question: My understanding is gelcoat is simply colored resin, correct? If yes, why does everybody seem to use the clear resin?
Clear resin allows you to see when the glass is fully wet out (the glass goes from translucent to clear when it is fully saturated). I think this would be more difficult to see with a colored resin.
