TM 1-1500-204-23-1 (c) Attaching equipment damage.  Repair attaching equipment damage as follows. 1   Repair,   when   practicable,   or replace all damaged attaching equipment such as straps, buckles,  webbing,  keepers,  cords,  cables,  cable  fittings, grommets, etc. 2 Dip ends of all new webbing in a  mixture  of  50  percent  paraffin,  Federal  Specification VV-W-95, and 50 percent beeswax, Federal Specification C-B-191 3    Dip    ends    of    sash    cords    In shellac, Federal Specification TT-S-271. (3) Waterproofing.  Restore water, mildew, and weather resistant qualities of a protective cover by coating with water repellent textile finish compound as follows WARNING Solvents contained in the compounds    are    highly    flammable and toxic; therefore all work shall be accomplished  In  an  open  area  away from any flame (a) Stir compound thoroughly until uniform mixture is obtained. (b) Spread   cover   out   completely   on   a clean flat surface, with Inside of cover down. WARNING Solvents  contained  In  compound  may tend to irritate skin, therefore, prolonged contact shall be avoided. (c) Apply moderate application of compound to outside of cover with a brush or spray. (d) Apply  compound  well  into  seams,  as they are particularly susceptible to mildew and leakage (e) Dry   cover   thoroughly   until   odor   of compound has completely disappeared (4) Storage.          Store     protective     covers     as follows: (a) Fold covers neatly to facilitate easier and faster installation when covers are needed. (b) Store   covers   in   a   dry   place   on   a platform   or   on   slats   of   wood.      Never   store   covers   on ground or concrete. 9-23.  Armor Plating.  The repair instructions that follow are  limited  to  composite  armor  composed  of  a  ceramic facing  bonded  to  a  fiberglass  reinforced  plastic  backing. The ceramic facing is covered with a flexible spall shield to protect the crew members from ballistic fragments.  A rubber  molding  is  also  provided  on  the  edges  of  some panels for crew protection.  These repair procedures were developed   with   the   objective   of   matching,   to   a   high degree, the original strength and ballistic properties of the undamaged   armor   panel,   with   a   minimum   increase   in weight.    Extending  the  service  life  of  armor  panels  will facilitate the mission capabilities of organizational units by the effective use of material assets.  The ceramic facing may consist of one of the following materials. • Aluminum Oxide (AI203) • Boron Carbide (B4C) • Silicon Carbide (SiC) a Armor  Plating  Inspection  and  Repair  Definitions. Table   9-6   gives   definitions   relative   to   inspection   and repair criteria. b. General Inspection of Armor Plating. Radiographic inspection of the assembled armor panel is the   primary   method   used   for   nondestructive   testing   in determining  the  extent  and  location  of  internal  damage. The  radiographic  skills  and  equipment  required  for  this type of testing, while available at Depot installations, are not   available   to   Army   field   units.      Therefore,   for   field units,  a  visual  inspection  of  the  panels  must  be  made, which requires removal of the nylon spall shield.  Remove the   edge   molding   and   peel   off   the   nylon   spall   shield. Exercise  care  when  removing  the  spall  shield  to  avoid damage    to    the    cloth.        Use    the    following    inspection procedures. CAUTION Handle armor panels with care. Ceramic    tile    is    brittle    and    cracks easily. 9-48
