Damp in a repair

[GlassStarz]

there are a couple different views on dry out solution it brings the evaporation point down so you dont need to heat as much or as long some feel it is harmful to the pv layer others say it is there for only a little while and not long enough to actualy do any damage. The arguement is that bringing the pv layer to more extreme heats for longer times without it is much more harmful to the pv layer than adding dryout to the break. Its kind of like the Ford Chevy debate you are not going to change someones mind on which is best my solution to years of dealing with the cold and wet was to move to a warm climate

There is also some evidence that it does not actually lower the boiling point at all. Some research has suggested that all that happens is the additive evaporates away first leaving the water behind. As you can imagine we have experimented with it for a long time overe here.

Hello all . if you look at two repairs which are identical ,but one as moisture in it and one does not how would they look different.

If only it were as easy as that just look at it and know whether it has moisture often you see a dark spot but that can be air just as often as it is moisture
Guys like screen see moisture everywhere because of where they live so they treat every break like it has it I live in a area with little moisture so I dont always look for it and sometimes you get suprised so recently I have gone to treating everything like it is wet
(Im pretty sure screen dreams of water)

i do to , i live in Blackpool i just got soaked walking the dog on the prom .I think I will treat repairs the same way as you .my other concern is uv can you buy the uv shields and is there a none uv level which is safe to work in without shields .

Water has the same refraction index of glass so it is difficult to see, in your area every damage will be wet.

Good point screenman, the water will mix with the alcohol, or acetone. the problem is it needs to be agitated to accomplish this. The theory is that when mixed they will evaporate more quickly. Not true, use the dristar and your done. Now if you got bad gas, (water in it) you can use alcohol to burn it off, that is what the gas dry additives are.(Alcohol) Much cheaper too, it mixes with the fuel and allows it to burn off. I doubt that it is effective in the WSR application though.

You can buy UV shields from me, we have yet to find a non UV day in the UK, I would suggest one may not exist.

Not quite true anyone who has lived in freezing environments can tell you no agitaion is needed just dump the dry gas into your tank give it a couple minutes to work its way through the system and give it a crank the stuff dilutes into the solution if it works with 15 gallons of gass now figure what a miniscule amount of water is in the break after you add the dry out and hit it with the heat the moisture is gone
The most popular type of dry out machine is made from a cigarette lighter coil I watched a old timer use the one from his car over a break one time. I asked him why his answer was "Cause im not dumb enough to pay a hundred bucks for something I got free with the truck" LOL

The tests with the dry out solutions was carried out by one of the universities over here not by myself. So maybe they are wrong all I know is I have stopped using it.
