With the techniques and products shown in this video, you can confidently repair and
refinish damaged textured bumpers and trim.
This Honda CR-V lower is fully textured and has two gouged areas that we will repair.
First, clean the bumper with 1020 Scuff Magic and water.
Use a scuff pad to spread the soap and get down into the texture.
Rinse off the soap and allow it to dry completely.
Spray 1000 Super Clean Plastic Cleaner in a heavy wet coat to dissolve mold release agents and silicones.
Before it evaporates, wipe it off with a clean paper towel.
The first step will be to fill the gouged areas.
To prep for the filler, sand with 180 grit sandpaper to roughen the plastic and to round off any sharp edges.
Don't use 80 grit paper.
This type of plastic is too soft for coarse paper,
and 80 grit will create deep scratches and fuzz that will be hard to refinish later.
Prior to applying any coating over raw TPO, use 1050 Plastic Magic Adhesion Promoter.
Spray a medium wet coat over the area to promote a good featheredge.
Allow the Plastic Magic to flash off for about 10 minutes before applying the filler.
Mix cream hardener into 1047 Putty Flex flexible polyester glaze.
Apply Putty Flex over the gouged areas.
Allow at least 20 minutes for the Putty Flex to cure, then sand with 180 grit paper using a DA or a block.
The next step will be to apply a primer surfacer over the area to fill any sand scratches.
Again, before spraying primer on raw TPO, use Plastic Magic Adhesion Promoter.
Spray a medium wet coat over the area to be primed and allow it to flash for 10 minutes.
Prime the repaired areas with 3043 All Seasons Black Jack Waterborne Primer Surfacer or something similar.
After the primer dries, use 320 grit to sand the repair area smooth and to blend back into the original texture.
Also, sand the entire area to be retextured with 320 grit.
Do not sand off all the texture, simply scuff sand to flatten the texture slightly
and to rough up the surface for better adhesion.
The final step before spraying the texture is to apply Plastic Magic Adhesion Promoter
over the entire area to be retextured.
In this case, we will retexture the entire bumper for the most uniform appearance.
The Honda CR-V has a medium texture.
We will use 3803 Flextex VT texture material.
The Flextex VT allows you to vary the texture by reducing the paint with lacquer thinner.
For a coarse texture, spray Flextex directly out of the can with a 1.8 millimeter primer gun with no reduction.
For a medium texture, add 25 percent lacquer thinner and spray with a 1.3 millimeter gun.
For a fine texture, add 50 percent lacquer thinner and use a 1.3 millimeter gun.
In this case, we are going to cut it about 25 percent
since the texture is somewhere between medium and fine.
Adjust the air pressure to about 40 psi, and open the fluid needle fully.
Spray from a normal distance.
Test on a piece of masking paper to get a feel for the proper speed of pass.
Lower air pressure for a coarser load.
Increase for a finer texture.
We will be spraying three or four light coats to allow the splatter effect to build to achieve the desired look.
Apply the first coat of Flextex VT.
Again, spray from a normal distance, but move the gun quickly to prevent wet spots.
You're trying to splatter the paint on evenly, not flow it out.
Allow a few minutes between coats for the solvent to flash off.
Apply two or three more coats until you get the look that you want.
When you're done, let the Flextex dry for about 30 minutes.
Scuff the Flextex with a grey scuff pad to knock off any high spots or dry spray.
To restore the original color, it is best to topcoat the Flextex VT with Bumper and Cladding Color Coat.
This paint can be intermixed to match virtually any OEM plastic color.
In this case, we have mixed 3734 Honda CR-V black color.
Bumper and Cladding Color Coat is ready to spray with no reduction.
Also, Bumper and Cladding Coat does not require pretreatment with adhesion promoter.
It sticks to raw TPO right out of the can.
Apply one or two even medium coats of Bumper and Cladding Color Coat.
Move the gun pretty fast; you're not trying to flow it out.
When you're finished you'll have a textured appearance that simulates the original.
