I have used all of the products above and I use to powder coat out of my shop as side income when all the local places had shut down.

If you bedliner use the U-POL kit. It isn't much (120 with the gun) and has a really nice texture when sprayed and is UV stable. I also believe it is a stronger coating than the others. Bad part is since you add hardener to it you can't just open the can and touch it up.

I prefer powder coating because you get a nice tough coating that looks really nice, is very uniform, and comes in a variety of textures and colors. Unless you have the powder and the right materials you can't really touch it up either. Removing powder coating is really tough, I have yet to see a properly prepped part fail after being bumped. Also depending on your area it can be pretty cheap, last load I took in to have done cost $60 stripped and coated.

All in all both have their ups and downs, if you keep your bumpers from hitting stuff too often powder coating will last a long time and can always be dipped and recoated.

Geez.. I must be the unluckiest guy in the world..
Because it seems every piece I buy that is powder coated.. the coating fails within one year..
..and not just little chips that can be touched up.. But it cracks or chips a little then corrodes under and sheets of it come off in the following months.

I trend towards cheap rattle can.. You can see when it begins to fail.. and then just ht it again..
Easy to maintain.
Easier to repair.

Update -

Deciding to go appliance 'epoxy' rattle can (not really epoxy since it doesn't have a catalyst)

My thought is I used that successfully in other applications and holds up well.

In my custom bumper/swing away designing I'll be making changes periodically and this will allow me the flexibility to do so without affecting higher dollar powder coat or 'gooping' it up with bed liner - if I have to grind some of this rattle can off its easy..

When I feel my design is 'finalized' I'll take to powder coater. Since they do a total prep, I'm not that worried if I get some rust / paint imperfections in teh mean time since they'll clean that up.

Many dislike Eastwood products but these have held up very well in my testing.
The can is really cool how they keep it separate until you mix it:

http://www.eastwood.com/paints/2k-aero-spray-paints.html

Once mixed, run out the can, it doesn't hold past a few hours.

Yes, extremely expensive by the can, but if you lack the HVLP equipment, you cant beat it.

Exclamation Wear full on safety equipment when spraying 2k products, even from a can. Cover every inch of your body, protect your eyes and use a respirator that can handle chemicals Exclamation
