i've asked in the paint and body section and no one has given me an answer and i also searched it....so hopefully there is someone out there that will give me an answer..

i picked up a bumper and its got some deep deep scratches on it (so bad its like the plastic is actually what i feel when touching it) . i was wondering how i would go about getting rid of those before i get it painted and put on my car. sand it? bondo it? sand and bondo? i really have no clue since i've never done anything like this before but i got the bumper for free so i figured i have a free chance to do it myself. all help is surely appreciated!!!

 

You can put the bond on it and then sand it down. I would also wet sand before painting.

 

where can i get bondo from?

 

Any parts store, pretty much
Autozone, advance auto, murrays...all should have bondo. Hell, Ive seen it at home depot

 

dont use bondo itself, bondo make a glaze filler, its a tube that you buy and its used for fillin in minor imperfections... it will be less messy then bondo

 

thanks guys!!

oh and what grit should i use for sanding it after i get done filling in the spots?

 

sand off the scratches so that its all smooth then simply spread a little glazing putty over it from the tube with a body filler spatula,smooth that out and get it relatively flat.
sand it off,then repeat if needed.I would start of with 220 and go up from there,220-340,480..
