If you've got drafty windows, chances are you're not going to be opening them in the cold weather. So why not seal the cold winds out temporarily?
DAP Seal 'N Peel weatherstripping caulk is designed to be peeled away in three to six months. The solvent-based clear caulk comes in 10 oz. tubes and is applied like painter's caulk. At $5 a tube, the caulk can be especially useful where storm windows or shrink-wrap applications are impractical or too expensive. A single tube covers 56 linear feet, or about 4 average sized windows.
The caulk forms a watertight and weatherproof seal, although it is not recommended for areas that will be under water. Use it indoors or outside. It peels away easily and will not mar cured painted surfaces.
In addition to windows, DAP suggests that the caulk can be used to seal seasonally used doors, vents, fans and air conditioners. The caulk can withstand temperatures of -30 to 150 degrees Fahrenheit, including freeze/thaw cycles. In addition to wood, the caulk will stick to glass, plastics, ceramics, aluminum, fiberglass, metal, porcelain, vinyl, drywall and concrete. It dries to tack in about 10 minutes, and cures completely in 24 to 48 hours.
So what's the drawback?
Like all solvent-based caulks (the solvents keep the caulk flexible) Seal 'N Peel gives off noxious fumes while curing. Homeowners reviewing the product give it high marks, but nearly all complain about fumes. The material safety data sheet from DAP notes that until it dries, the caulk is highly flammable, and a respiratory and skin irritant. It's also harmful or fatal if swallowed.
You can minimize the effects of the fumes by using the caulk while it's still warm enough to keep some doors and windows open for ventilation.
