Hi Everyone,
 
I apologise in advance as this query is not directly to do with VWs
however since all of you with Westys
& similar campers have canvas sides to the pop top, perhaps you can
advise...
 
I am looking for suggestions as to an effective waterproofing agent for
canvas. While brand names are welcome,
the fact that I am on the other side of the world to most of you means
that such names may not mean much here
so what the most effective modern treatments are is I guess what I'm
primarily after. 
eg. Is there a silicone spray available for this application? 
 
Years ago I recall canvas for trucks and railway goods wagons being
treated with stuff like heating & applying evil 
mixtures of paraffin and benzine...however I doubt the people who did
this work are around anymore to tell of their 
experiences...
 
I need to treat the canvas roof of my Landrover as I am tired of water
dripping down my back in when it rains as well
as onto the dash...and the chance of water mixing with old English
electrics is indeed a scary thought...;-)
Also, my side mounting Kombi tent is some kind of thinner more modern
canvas material that eventually also may 
need to be treated (hey, there's OVC after all ! )
 
BTW replies saying to check the archives are not necessary as I have
already tried that and curiously got no matches
to "canvas" and "waterproofing"...WTF?
 
Anyway, thanks if you can offer any suggestions...
 
Cheers,
