How will this hold up in a car wash? I have just a chip in my windshield

I have not noticed any failure in the repair at all - including repeated car washes. All looks good months later.

how many repairs can i do with 1 kit? or is it single use only?

It appears you can make several, depending on how large the damaged area is. I made two very small repairs and have product left over.

Will this work on home windows? I have a small area outside a double-paned glass window; I'd like to patch it before it expands and breaks the seal.

Bad idea, it will be forced through and run out the other side of the glass pane as there is no membrane to hold it in like on the 'sandwich' type of safety glass used on windshields. You won't be able to get to the inside to wipe it off. You might try applying the resin to the outside without the pressure pump, just carefully press it into the crack with a plastic scraper. if you can remove the window lay it flat first if the crack isn't loose enough to let the resin leak through. Follow the curing instructions and it might (or might not) do the trick. However, if the glass is cracked, then the seal to the dead space (or gas filled space) likely has already been breached.

Does this kit come with a razor blade?

Mine came with a cardboard cover for the razor blade but no blade, unless I dropped it in my chair while opening it. OUCH, I hope not! The blade and curing strips are hiding inside the folds of the instruction sheet.

Rain-X Windshield Repair Kit is easy to use and installs in minutes. Removes air from breakage and is filled with durable resin, making it stronger than ever.
