Prosoco R-Guard Fast Flash

This stuff is amazing dries fast and is super strong and flexible. I will be buying again.

Works, but a little spendy. Need to sell a 2, 3, 4 pack for cheaper or something

Pretty easy to tool even in cold temps, initial tack very good, sag resistant but self levels a bit (I probably used it where I shouldve used the joint filler in some cases.) Is just nice to work with...when paper towels are readily available to keep the spreading tool and all of ones clothing clean. I cant review the properties I cant test such as breathability etc but itd have to be far better in that regard than the off the shelf caulk type products.

Exploded in my $50 gun. What a mess.

A great fluid applied flashing, works with a sausage gun. Working time of the flashing was as described, and it bonds very well.

Product was fully expired when received. Only out a week. I used it anyway as it went on a personal project but would never have installed it on a job. It is excellent product though!

With weather in the 40s I waiting a few hours to get it to setup. Tried closing off the area with heat gun and space heater, but it didnt help. It didnt setup. Ultimately I gave up and installed the door in the wet stuff. Its messy. Cleaning the gun sucks afterwards. Needed acetone. That helps. Pricey. I did just the bottom of the door and it took an entire role and a half. Dont know maybe I used to much. Thats why it didnt dry? I would recommend if the weather is warm and your installing the windows door the next day maybe.

Can be tooled after application. Makes a great seal on OSB. Is fantastic flashing for those areas where metal flashing will just not work well.

Pay attention to the date of manufacture, it has a shelf life of 12 months. Like others mentioned, product arrived 3 months out of date and didnt properly cure. This is a basic silyl modified polymer, there are lots of other better products out there. I ended up going with 3M Adhesive Sealant 740 UV, which was half the price and a much better product.

this stuff is better than others I have used just too expensive. if you need to seal a small area this is the product you need.
