Have a small crack in my windshield. How well do those repair kits they sell at Walmart or car stores work, specifically the Fix a Flat brand windshield kit?

 

you have two cheap solutions for this cracked windsheild problem of yours...

one go find a small tree, get a truck and run it over the day after a big storm, lay it across your car and call the insurance company, tell them you were cruisin along and a tree fell on your car...a whole tree....

or tell then you were passed by a truck or something and a rock hit the windshield....

say the hell with fixing it if it's broken....too much work, too much money

 

go to pepboys and they have a glass company that will come to u and repair chips, cracks, and i think scratches also. but they will repaire it while u work or while u watch. ive seen it done and its pretty cool and they do a good job on them too.
