undercoating peeling off

[andybla]

Hello, Last weekend i sprayed on some freshly undercoating to the sides from the wheel wells, i dit this first because i still need to weld on something that when it is weld on, i cannot reach those area's anymore that i have sprayed undercoating on now.

So what i did was leave a taped stroke open where the piece needs to be welded so i can put welding primer in between etc..

What i notice is, while the undercoating is nicely layed on, it stays gummy/rubberized (which i think is ok?)

And you can peel it off easily, is this normal with undercoating? I did scuff it up and degreased the surface, it's like plasti dip peel off type ...
