do scratch removers/chip fixers work??

hey everybody, i recently realized my car has alot of bad paint blemishes like a bit of rear bumper spider webbing, i bought the car not noticing it had been keyed and hardcore egged at least one time in its life, and i also have a few small paint chips on the front .
i dont want to spend a bundle repainting cause honestly its not worth it financially to me (its my winter beater). i read alot of ads about meguiars scratchx and langka blob elimanators etc etc.. and everything sounds great but does anyone out there know if they actually work like they say??

i trust the detailing pros- i bow to your detailing superiority : ) thanks-

Scratch X worked great for me but it really depends on how deep and how bad the scratches are. Its not a miracle worker though...............
