20. ABSTRACT (Contlnu 



Coating materials and cleaning and application procedures and equipment were 

 developed for use in the repair of damaged coatings on Navy steel antenna towers. 

 Experimental coatings were screened by laboratory-accelerated testing before field exposure. 

 In the initial field exposure, 19 of 32 different coating systems provided good protection 

 from corrosion for 3 years to a steel antenna positioner in a marine atmospheric environ- 

 ment. In a later field experiment, 8 of 12 of the better -performing coating systems cont.
