Interprotect Watertite YAV135 is an excellent 
fairing compound due to its unique two-phase 
cure, which gives a long
easy-to-sand window. 
Interprotect Watertite YAV135 can be applied 
to a thickness of 3/4? without sagging and its 

superior spreadability makes it an ideal glazing 
compound for filling small nicks and scratches. 
Note: Epiglass
Epoxy Resin can also be used 
as a fairing compound when mixed with HT440 
Filler powder. For MSDS information please
