Excellent for Energy Efficiency Projects
[This review was collected as part of a promotion.] This product is easy to use, strongly bonds to all types of siding and windows products! After using OSI Quad Max, I will not use any other caulking products. I used this product on a siding installation during cold, wet weather and had such great results. I was very pleased with the smooth finish.

Great wet application
[This review was collected as part of a promotion.] I needed a product that I could apply in the rain. Quad Max worked great. We sealed a leak along a masonary wall where it met a metal window frame in a light rain. The window was leaking and it stopped. Thanks OSI

when you get it out of the tube it does what it says
3 out of 12 unusable... broke seal but would not flow out except from the bottom... ruined caulk gun
definitely for pro use only... unless you like working with marshmallow cream like sticky mess that can only be cleaned up with mineral spirits

We inherited a caulked deck (never wouldn't have caulked if I'd built it myself...!). Not too pretty now, but this repair will get us through the winter, and then we'll finish stripping the paint next spring and stain the deck. The space below is staying dry so far. Fingers crossed! Strongly advise using a power caulk gun to apply, as it's stiff and thick.

Need to offer the full range of colors
This review is not about the product. OSI is a very good product, but that is not the issue of this review.
I just happened to find one of the colors that I needed. The other color I needed was #004 Arctic White and it was not available. If you are going to offer this product for sale, you should offer the entire range of colors manufactured. I could understand if some colors take longer due to stocking issues, but the current system is hit-or-miss. I ended up buying the two colors I needed from two different sources.
