If humidity is high i dont think it will dry. For example in the evening if air temperature drops and RH goes near 100% it will stay wet till morning untill air temperature goes up again. So best to not work in the evening, and look at the weather.
I have my doubts. Tip.... use a small soldering torch to dry the joint. It'll vaporize the water between the gutter laps. Then three-course...... Keep um coming.
An I had a rubber rod put on my exspandoo which I believe the exspandoo is my proble where it connects the the main trailer it’s always leaks around there it doesn’t in the exspandoo roof cause of the rubber roof I just don’t have the money to do the rest but if I can find somthing to use to level the sink hole I believe would be great
Nice fix Doc; perfect application for these products, would you still apply silver paint for UV protection? Play safe from Elliot Lake, Ontario, Canada.
So, if that paint would peel, then surely after 30 years it would show signs, duh. The entire gutter has not 1 bit of peeling. When you stop water and oxygen reaching metal, you stopping rust.
