Q: Will can spray overhead? switched recessed lights to cool led & want to fill wood box holding recessed light can to sop heat loss.

Since they recommend turning the can upside down to clear the gun for storage, it will not spray that way, however you can attach a length of clear tubing to the spray tip and get an overhead gap filled.

Q: What is coverage at 1 inch thickness

Thank you for your interest in our product. The yield on this product is each can will cover 970 linear feet based on 3/8" bead of foam. Unlike the 2 part foams, this product is meant for gaps of 3" or less. Thank you

Q: How many cans do I need to spray under my 21 inch acrylic tub?

you have not provided enough information to answer the question. Clarify the size of the area you want to place this foam. Do you plan to just fill the area under the bottom of the tub or completely around the total under side of the tub - bottom and side walls? Example for bottom of tub: 20 inches wide x 60 inches long x 4 inches high. Given these dimensions there is plenty of material to fill that area. If you plan to go around the sidewalls - you will need a few more cans which you can buy at a hardware store.

Q: will it work on metal siding on concrete?

This will stick to both surfaces.
