Anybody tried SEM Multimax paint?

[Gruelin]

Currently applying POR-15 on my new rear 4xInnovations bumper, and exploring topcoat options.

Anybody tried SEM Multimax (formerly Promax) paint on a bumper? An option because it comes in a rattle can.

SEM makes quality paints, so it should be better that a Krylon or Duplicolor, but I can't find anybody who's had experience with the Multimax paint at all.

Thanks for any stories about it!
