Some of the cracks I can actually feel with my fingernails, but most of them just look like dark spots. I'll have to use the primers and coatings everyone has mentioned, thanks

Hello, I saw in your pics the stress cracks or spiderwebbing. USUALLY it is just the paint that gets cracked. In the pics it looks like the bumper has cracks BUT it is just where the cracks in the paint have let in moisture or other contaminents while driving. You should be fine sanding to the plastic, yellow bumper and then plastic prime the bumper follow with a urethane primer. You will see as soon as you prime if the cracks are gone. 99% of the time here at our shop the cracks are just in the factory paint and undercoat. Good luck. Ron
Yup that's what I found out when I stripped my bumpers it was just in the factory paint sanded all the old paint off then used the urethane primer looks like a new bumper cover.

Still sanding. Mostly to get the paint off. I've found the majority are in the factory primer so they go away. Any of the deeper cracks take alot of work but eventually go away. Once I get the deep ones mostly out I can move up in grits to get ready for primer. I don't need to sand all the paint off areas without cracks do I?
Any progress? I just stripped my bumper, most of them disappeared but I can still see some. I'm getting it painted in two weeks.

Almost done with the 80 grit paper. It takes a while but they eventually go away, im working up to 600 grit before I take it in. But I'm not in a hurry because I've been saving money and spent the last week in Michigan.

Do you have any scratches from sanding with 80? I just finished taking all my spider webbing out today and there's some scratches. Here's some pictures
I did, 80, 180, 320 then the scratches were there, tried 400, 600 and 1000... when I did 80-180-320, I kinda skipped the 180, I just lightly went over everything < 5 min

There are a few but not nearly as many. I would just go back over with the 80 until you can't make one the distinct scratches. I did 80, 120, 320, 400, and 600. Mainly because that's all my local store had.

His is a OEM WS6 hood. Right now it fits like ****, but that's only because the car was hit in the front before and not repaired correctly. That mess will be lined up soon enough. OEM hoods are by far the best fitment though.
