Looks like it wasn't prepped correctly when it was sprayed black. I'm no pro, but i would start by sanding off all the black paint. I wouldn't try to use any stripper unless you want to take it down to the plastic.

Sand it down until it's even. Take it down until you get to the red paint underneath. I'd start with 120 grit then progressively work up from there (120, 220, 300, 400...). Use a sanding block where you can. A good paint job starts with a smooth surface. Continue until it is COMPLETELY smooth. Then prime with a plastic paint primer.

Anything you can feel or see will show up in the paint.

That bumper is suffering from poor adhesion or it had something hit it and start the spiderweb process.

Both can be remedied by spraying Dupont 222S (adhesion promoter) before you spray the sealer/base/clear over the sanded final primer coat.

Also, a flex agent *should* be added to the base/clear going over flexible parts like BUMPERS etc.

Throw it away and start with a fresh piece. The bumpers are cheap in comparison to the material and hours of labor you will spend making it look good. After your all done, it might just crack again anyway, so its better to start with a good clean surface and paint it with the right stuff.

Appreciate you being a perfectionist but I think this bumper is deff reusable and can look at good as NEW without costing me as much as starting from scratch..

You could sell it for $150-$200 to someone else who thinks they can make it look like new on the cheap and buy one from Mentormitsubishi new for $317.31. They used to sell them already painted but I think they only come in red now. Trying to make the plastic smooth and do a permanent paint job on a part thats been painted a few times and has cracked paint is not an easy job for anyone, especially a novice.
