Hi,
On my 2004 Buick Lesabre I am fixing some surface rust spots. I don't want to go into details on that, but I am going to be sanding the rust/paint down to bare metal and using self etch primer, base coat, and 2k clear to do that. Getting spray cans from Sherwin-Williams Automotive. While I'm at it I feel like I should look into doing these plastic bumper scuffs too. Can I use regular primer, or does it have to be a special plastic adhesion primer?
I am also not sure how to go about prepping and painting these scuffs.
Thanks

I should probably 'sticky' this post - take a look at my response to this topic which is very similar to what you are asking about:

Chris, that would make a great "sticky." Any chance we could put it at the top of our Fiberglass section?

I was at Sherwin Williams Automotive the other day and the guy told me that I just need to primer and paint the bumper and don't need special plastic adhesion primer. He said I only need adhesion promoter when painting a new bumper. He also asked if it is hard plastic or flexible plastic; it's flexible.
I am trying to at least paint over that 1" x 8" scuff on one side of the bumper if possible. Do you agree with what the guy told me? I am also wondering where I should be looking for sand paper. It seems like it could be a waste if I buy a pack of each grit I'll need. |
If there's factory primer in those spots it'll be ok. If it's really down to raw plastic it should have adhesion promoter. There's a good chance it'll be ok for just those small spots but if ever tapped there again it may be prone to chipping/cracking easier.
On the sandpaper most auto body supply places will sell you single sheets. |

It's down to raw plastic. Is there an alternative to the 3M 5907 adhesion promoter you linked to in your bumper repair sticky? I am only doing a small area so would be nice to get something in either a smaller can or in a small applicator, that is relatively inexpensive, etc. |
If you hit a Pep Boys, Autozone, Advance Auto, you should find Bulldog in an aerosol. In my opinion the 3M is a better product but for what you are doing the Bulldog should be fine.
