I have some going on in my front bumper, as I'm sure many if us do. Anyone know what to do about them? I have sanded down all the paint but i can still see some of them. I don't want to go too deep but don't really know what to do. Would a few thick coats of primer with flex additive do the trick?

I used a 2 part compound kit from the store called "Flexible Rubber & Plastic Patch" in the automotive section

 

Did you go all the way to the bare plastic? The spider cracks usually go down to the GM primer. Honestly I think you have to remove all the paint on the bumper and use a plastic parts primer that works with your chosen paint system.

 

A few coats of primer filled mine in on the back bumper when I repainted my car.
