[quote]are you saying you painted it 2 months ago and it is lifting now?
I painted all the texture peices on my 03 silverado. I scuffed with a grey scuff pad then used sem adhesion promoter and primed with sem flexable primer surfacer. sanded and painted. 4 years later the only problem i had was on the lower valance where I ran it into a rock.[/quote]

Yes, I painted it around 2 months ago.

SEM, makes excellent product and I was never confident in the dupont promoter. I’m going to order the SEM next time.

Jimmo,

Thanks for the info.

[quote]What is your prepping procedure? Also if you got a plastic code off of the moldings (usually somewhere on the back), that might be of some use.

Another thing that comes to mind are flash times from adhesion promoter to primer. Pre-baking your parts and using a plastic cleaner on them (while warm)can help you remove mold release agents on stubborn plastics.[/quote]

Prepping procedure as follows:

clean entire bumper with soap and water.

sand entire bumper with red scotch brite

spray promoter

spray primer

Ding, will I shoudln’t say edges but where the bumper bends and folds is where the primer tends to lift. Will I’m resanding the primer and will keep you guys updated.

Note: The bumper was painted two months ago. Since then it looked great but until now the problem has occured. I’ll try to attach some pics later on tmw.

Thanks guys
