Bumper paint prep

[newtopaint]

Hi all

Im new to autobody work and decided to try to fix up my old 87 sentra. I bought a replacement fender and that went in without much fuss. Im down to putting in a bumper cover but Im not sure how to paint it. The cover is a replacement primed with a hydroflex waterbourne acrylic urethane. It also states not to use a adhesion promoter. So Im guessing I have to scuff with gray scotchbrite, clean but do I need to use a flexible primer after scuffing?
I dont have a gun so Im going to give it a go with rattle cans. Im thinking about using that bumper coat product that Bondo and Duplicolor has for sale.
Bumper coat has urethane in it so Im guessing its flexy enuff. Anyone ever use this stuff? Is it any good and does it hold up over time? thanks all.

I've never used that paint but if it's like most urethanes you probably don't need any additional primer if the bumper has a coating on it. I'd say you could probably just scuff and paint.

Is this the semigloss black stuff?
I used bumpercoat something or other in rattlecans on an MGB a while back,pretty sure it was Duplicolor.
Held up OK for the money,just don't spill gas or any solvents on it!

Just did the job today, sanded with 600 paper, washed off dust with warm water and dish soap, isopropyl wipe to remove any oils and then sprayed 3 light coats with time to dry in between coats. Duplicolor flat black came out looking okay, just dont know how tuff the paint is.

Spilled gas on the rear bumper of the MG,wiped it off and the paint came with it!
I redid the bumper,was REAL careful about putting fuel in it,held up pretty good for the next couple years,untill I sold the car.

Fortunately, the bumper is the front so gas wont be a problem. I may do the back one to get the the front and rear bumpers to match. My next question is will I be stretching my luck if I try to rattle can the front fender too? I saw a few online paint stores that will match OEM colors for my nissan.
