     Hello everyone on the Europa Mailing List !

     the heat (30C) has made things tricky lately.>>]
     
     Jim Poole in the States has highlighted (IMHO) the downside of working 
     with composites; temperature and humidity control.
     
     I am about the same distance in to the project as Jim, half way 
     through the tail kit (early days !).  So I would also appreciate 
     advice from builders who are further down the track. 
     
     The 'good book' emphasises the importance of a warm and dry workshop. 
     It is summer here at the moment (Yorkshire UK), with my insulated 
     garage it is quite easy to get the temp up to 32 C and RH down to 45% 
     (+-5%).  (The heaters I use are two 1.5KW oil filled radiators)
     
     The trouble is when I go in and start working I am soon perspiring 
     pints ! (Yuk ! I know, but I have to tell the truth :)  ). 
     Consequently the humidity begins to rise. By the end of a lay-up it is 
     back up to 60% even though the temp is 30+ C. As soon as I leave it is 
     back down to 40%. Basically I am the problem !!!!
     
     (1) Does anyone use a lower temp and accept an (initially) higher humidity?

     (2) Does anyone use a dehumidifier ? 
     (3) Any (survivable) ways to stop perspiration ?
     
     
     Thanks in advance for any comments.
