Visit http://www.refinishnetwork.com for more auto body repair information. This is a bumper repair on a Chrysler 300 that has a split in the rear bumper cover. Shown here is Kent Repair Epoxy adhesive, Evercoat Polyflex and BASF urethane primer.
To start the bumper is washed to inspect for further damages. There is a small tear that may not be visible on the video but there is a clear hole in the cover.
The hole is first tapered out on both sides and reinforced on the back and front with epoxy. The epoxy is sanded fairly straight with a DA sander but final blocked with flexible polyester putty. You can simply finish in epoxy and it would make for a better job, however it sands much tougher.

This shows a minor scrape on a Mazda Miata. The scratch was feathered out,
primed and painted using BASF paint. There are many ways to get the job
done, this is what was done here:
1. The scratch was feathered out using 280 grit paper until each color was
seperated around 1/2".
2. Next it was backsanded to allow space for the primer to adhere.
3. It was primed with 2 coats of Glasurit 285-10/20 direct to metal
urethane primer and allowed to dry. It was primed with a devilbiss
finishline HVLP gun with a 1.6 tip.
4. Next it was blocksanded using 320 paper, then final sanded with some
400-500 grit paper. Using a block is optional there but recommended.
5. After taping it up it was painted using RM Diamont basecoat in 3 coats.
Each coat was allowed to flash about 5 minutes before the next one. Then 15
minutes before clearing. An Iwata LPH400 was used to apply the basecoat at
about 20 psi.
6. The clear coat used here was BASF DC5335 Glamour clear. It was applied
in 2 coats with about 10 minutes between coats. It was applied using an
Iwata W400 with about 26 PSI at the gauge.
A few dirt nibs were colorsanded and polished afterwards.

This is a little run left in the clear coat. It is removed with no
ghosting by applying polyester putty over the run first, then sanding it
down flat and polishing to shine.
It sucks to have happen but every painter has had a clear coat run from
time to time. Removing a run takes some patience and time. but you can save
a paint job when its done right. Let the run dry thoroughly before
attempting this of the run can tear up from the clear coat.
I have gotten many clear coat runs and many have resulted in resprays, as
time goes on you get better and it happens much less...some clear coats are
more prone to run then others to so consider changing your clearcoat or
equipment set-up if you keep getting em!
Repairing and retexturing a Ford Explorer bumper cover
This video demonstrates, from start to finish, how to repair a textured
plastic bumper cover using a hot air plastic welder. After the plastic
welding is complete, the dents and low spots in the bumper are filled with
epoxy filler which is then sanded down to match the original contour. The
bumper cover is then retextured with MicroTex texture material from
Urethane Supply Company. Finally, the bumper cover is painted with Bumper
and Cladding Coat so that it matches the original color.

Repairing Urethane Bumper Covers with an Airless Plastic Welder
Urethane bumper covers are often discarded because of cracks and tears.
These bumper covers can easily be repaired using the airless plastic
welder. Because thermoset urethane bumper covers do not melt, you will not
be able to get a true fusion weld. The repair you get is similar to a
modifying/repairing your bumper with fiberglass
This is NOT a job of a professional. I just got to this point by trial and
error, and it is working for me quite well.
There are some steps missing that i forgot to capture on film, but if there
is any interest in this, i am planning on doing some work to the rear
bumper and i can make another (more detailed) video.
