Is there anything out there that will strip paint off bumpers that won't soften the urethane? or should i just sand old cracking /blistering paint off?

If you have a local paint/body shop supplier company they should have a spray can product made for stripping paint off of urethane bumpers. I think I used two cans on my rear bumper cover.

I think the cans are 20 ounces and have a gray label. I will look tonight and see if I still have one and get the part number and description off of it.

find a shop that does bead blasting. best bang for the buck.

New front Urethane bumpers are available. Most of the old urethane bumpers are starting to fall apart. You might just want to buy a new bumper. Before I got my car painted, the body guy showed me how the old bumper was starting to crack and fall apart. A new Front Bumper was on his doorstep a couple of days later... About $250 or so.

Note: Front bumpers are available, Rear bumpers are not. (AFAIK)

Sorry it took me so long to reply.

The bumper stripper is made by SEM. Part #39913 It comes in a 17 ounce spray can and it cost me $9.43 each.

It works pretty well. But you have to use it in a well ventilated area.

Thanks for the feedback gonna try the sem stripper first would have gone w/ bead blast but cant find any one to do it
