Spider cracks?
 

I have a ton of spider cracks all over my front bumper any way I can fix it

There is some good posts on here about how to restore a front endura rubber bumpers. From what I have read you need to V-grind out all the cracks and use a 2 part flexable filler to fill and finish the bumper with. I am using Dominian sure seal flexable bumper repair which is a 2 part epoxy filler that sands very nicely. Then from what I have read you should not use filler or polyester type primer. You should use epoxy primer. This is my first attempt but here are some pics of what I have done so far. The Dominian sure seal stuff is flexable. I have tried to push on the bumper after a couple coats and it has not cracked if that means anything. I am going to let it sit for awile to see if it stays flexable before priming.

Here is a pic of the bumper before grinding out spider cracks. These cracks were the same when the paint was still on.

forgot to upload. here ya go

Have you removed the paint and primer yet? Just wondering as it's hard to tell what's cracked until you get all the coating off.
I used the 3m flexible bumper repair stuff. You can get it at Advance, etc.
As was said above, there are a LOT of posts here on refinishing endura bumpers.
