MAINTENANCE MANUAL
CHART 1
LIST OF MATERIALS (THERMOPLASTIC REPAIRS)
(6) The patching compound is mixed in equal portions on a hard flat surface using a figure eight
motion. The damaged area is cleaned with perchlorethylene or V M & P Naphtha prior to
applying the compound (see Figure 3).
(7) A mechanical sander can be used after the compound is cured, providing the sander is kept in
constant motion to prevent heat buildup.
(8) For repairs in areas involving little or no shear stress, the hot melt adhesives, polyamids which
are supplied in stick form, may be used. This type of repair has a low cohesive strength factor.
(9) For repairs in areas involving small holes, indentations or cracks in the material where high
stress is apparent or where thin walled sections are used, the welding method is suggested.
(10) This welding method requires a hot air gun and ABS rods. To weld, the gun should be held to
direct the flow of hot air into the fusion (repair) zone, heating the damaged area and rod
simultaneously. The gun should be moved continuously in a fanning motion to prevent
discoloration of the material. Pressure must be maintained on the rod to insure good adhesion
(see Figure 4).
(11) After the repair is completed, sanding is allowed to obtain a surface finish of acceptable
appearance.
