Yesterday I decided to do a small test you should all try it but I know most will not. Make a medium size starbreak and fill it with water just as if it had rained or there had been morning dew or whatever you lot call it over there I then left the glass in a controlled temperature of 28 degrees centigrade about 80 farenheit 28 hours later the end 2/3 of the legs still contain moisture.I can see that Rainx may be a problem if is was applied after the damage had occured but not if it had been applied before as the pit would not contain any Rainx as it has a piece of glass missing.

I restate moisture is the biggest enemy of windscreen repair techs.

I welcome any comments on this reply but please try to make it technical not personal.

Good post Screenman I work on some fleet vehicles that the folks invariably will be washing during the time that I am there doing service. There has been a time or two when I did not check the moisture content until I had introduced resin and realized what was going on. Real bummer I could not think of a way to reverse the situation so I had to proceed with the repair and hope for a decent turnout. I found later that the moisture evaporated or what ever and the damage reappeared partially. I was able to follow up with a re repair and while the results were substandard I was happy that the shield 's were salvaged. I am more careful to watch for the situation now. We are getting rain again and the small amount of time that we don't have it here during the year is fast fading so I guess it won't be an issue for a while anyway.:icon_roll

I am also a new WSR Tech and am still doing some practice glass is there an ideal outside temperature?? inside temp, outside temp?? I ask because I have had some really good repairs, some not so good but have a digital laser thermometer could this be used to ideally identify temperature ?? Also what would you recomend for moisture removal ?? and last what are some of the things that you look for to indicate a high moisture content
