Not according to the wife.
That aside my guys at the local ppg dealer did a great job with advice and recomending products. This was my first auto paint project in years, first with hvlp. It was quite a learning curve, my son in law held the bumper up while I marked about 4 holes. I then drilled them and installed the bumper to look at fit and mark the rest of the holes. I cut the retainers in about 5 pieces to make install easier.
I had to add a little body filler at each end to make for a good fit, be sure and use high quality filler. After about 6 tries at fitment I had it pretty close.
I then built a stand to hold the bumper out of a engine stand and some emt conduit. after a good wet sanding with 180 and then 320, some glazing compound to fill a few pinholes, and then more wet sanding, I was ready to paint,NOT. No place to paint, off to the lumber store,A couple days later I had my paint booth built complete with exhaust fan to the outside. I have a nice large furnace blower I use in the garage to cool in the summer but it sucked the plastic off the booth frame, too strong, back to a small fan, worked great.
After talking to 3 different paint dealers in 3 different towns I settled on my local PPG dealer in wilmington, glad I did he has been selling paint for years and is fantastic to deal with.
A couple of pinholes in my filler  showed up after the epoxy primer coat that I had missed, my wife was kind enough to bring them to my attention Angry. That took several hours to correct, Note: do not try to put glazing compound over epoxy primer that is not well cured, bad idea.
I used a Harbor Freight Hvlp gun to apply the primer, the purple proffesional auto set of two guns, worked very well.
Next came the color, my paint guys recommended using the same paint, single stage  concept dcc that was on the car for a match. I had a partial can that had the formula from the previous owner so not to difficult.
I used a finex 3000 hvlp to shoot this, boy is it sweet.
After sanding and polishing I installed it on my car, you have to be careful and not pull the retainers to tight it will warp the edge of the bumper, and oh be sure and use a flex additive.
Lets see, cost of the bumper+ paint+plus gun+booth, what a deal.
Oh well, my son is painting his motorcycle in the booth, and I will paint a few things in the garage that need to be done, and the satisfaction of doing it myself,priceless.

Winston, it still is an excellent paint job. 

It's the wife's job to point out any flaws. Grin  Things others might over look, she has to make you aware of (a marital responsibility Wink).  That way you don't get a "big head".LOL  You can tell her all the guys here love it just as it is. Wink

Congratulations on a job well done.

Great job. Did you use a Urethane bumper or fiberglass. I used a Tureflex Fiberglass one when I replaced mine.

I found out the same thing when it came to mounting the bumper, the trueflex does not flex as much as the urethane bumper so I had to cut up the retainers to get them to fit. I also had to add some filler to the bumper flange because it pulled the bumper if I tried to tighten the nuts too much.

It is a truflex. I used a little filler on the sides, but not any behind the flanges.

I have discovered 1200 grit sanding and perfect-it rubbing compound.
Those hazy places on the fender where the previous owner didn't use a fender cover,  the scratches and orange peel he didn't sand all the way out, presto, gone. Actually several hours of hand sanding and machine polishing and they are gone.
I am amazed how nice it looks, I have done drivers side fender and hood, will do other fender this week. probably wholecar before its over.
