Bumper cover paint prep

I need to paint a bumper cover for my granddaughter's Honda and have zero experience with painting plastic parts. It's an aftermarket part made by TYG Products. Their information says it has a waterborne primer on it from the factory. Based on things I've read here, I should scuff it with a gray pad and paste and then seal prior to base. I've got SPI epoxy. Would that work as a sealer? I'm planning to use Wanda base {activated} and SPI production clear as I can get both from the same local store where I normally buy my supplies.
 
I've painted more of those TYG bumpers than I care to remember. :) There are two types of primer that come on those bumpers. One is a decent quality primer that has decent millage. The other is a thin coating that can actually be wiped off with solvent W&G remover.
So use a grey scotchbrite and sanding paste. Don't use alot of pressure when scuffing. Keep it light. When you finish look for any bare plastic spots where the primer has rubbed off. If you have the low quality primer on it there will be places like that. Count on using a coat of ad-pro if that is the case. Then proceed like normal.

Ahh yes the old tong yang bumpers! Industry standard in collision work lol. If they’re in good shape, I wash, scuff, seal, and spray.
