6. Place the GPS face down on the workbench and lift the warm plastic off the sheet, placing
it on the back of the GPS receiver and molding it around the GPS. This is shown in
Figure 5-40.
FIGURE 5-40: Mold the warm Concealex on the GPS.
Heating the thermoplastic to too high a temperature can not only damage the plastic but
also damage the GPS itself. Keep the temperatures to those listed in this chapter and keep
damp cotton cloths handy to cool the plastic quickly as it molds. If you overheat a sheet of
Kydex, it’s best to throw it away and start with a new piece.
7. Gloves and a piece of closed-cell foam can help you to press on the plastic to mold it
around the GPS receiver better. Use the damp cotton rags to cool the plastic down selectively
as shown in Figure 5-41.
8. Remove the GPS. You can now use a hair dryer or hot-air heat gun (or you can use boiling
water) to heat up small parts of the plastic to help you finish the molding process
(see Figure 5-42). Take your time at this stage because going too fast could result in a
mistake that takes you back to Step 1.
