For example, say you have an interior part, console, dash part, similar plastic, with a cigarette burn, crack or gouge or something and you repair and/or fill the defect -great, now you have a flat/smooth surface next to the fake vinyl texture of the plastic. 
What if anything can be done to return at least some of the texture so it's not like you have as smooth as a baby's butt next to textured plastic bits??|
Looks OBVIOUSLY repaired..... draws almost as much attention as the original crack or burn or gouge! Maybe more.

I have repaired cracked AMX quarter side sills, then restored the texture by using body filler. After sanding it smooth I carefully scratched the pattern back into it using an awl. It takes time but if done carefully the repair isn't noticeable at all.

Shelby Coleman was also working on restoring the finish to textured parts using a different method.

Sort of funny, really - I am out in my shop looking at the part again - thinking well if I don't get anything usable in the next little bit I'll have to just figure it out and make it work. Have to keep things moving along. 
My thinking in case all else failed - spot filler and some dental tools and picks and awls..... to try to match the pattern as best I could. 
And here you come suggesting basically the same thing. Worth a shot - there's always more filler if that fails. Wink

SEM 39853 Black Texture Coating Aerosol - 16 oz.

The professional body shops use this when applicable (vs. bumper cover replacement).


product details
TEXTURE COATING (SEM-39853) Texture Coating is a unique blend of flexible materials for restoring the textured finish on bumpers, dashes, fiberglass tops and other plastic parts prior to painting. Duplicates original textures Ready to spray Quick drying Topcoat with most refinish materials

Tricks to using the spray.
1. be very consistent with distant and speed of spraying
2. the number of coats sprayed will determine the thickness and texture of the part.
3. Use a small sanding block and lightly sand the surface of the texture spray after it cures. The spray will leave a very sharp top edge. When you sand the top sharp edges down the texture takes on the look of a textured automotive surface..

4. After the light sanding, I will either sand again for a flatter looking texture or realize the texture has not built up high enough, which requires a couple more coats of spraying the texture material.

I would practice before using. I have repaired numerous vehicle consoles using this product and the techniques described above.

Hammered texture paint works for some rough random sandy type textures on rigid parts, many plastics, etc. - but I'm referring more to the texture that is a grain-like pattern - longer patterns, directional, not a simple rough finish. Vinyl and other parts have longer fine textures you could trace with an awl, not a sandy dot pattern.
The texture I'm referring to would likely require some sort of film or piece to press into a paint or layer put on the part repaired. 
Otherwise the sand-like texture isn't too bad to do with textured paints. But vinyl usually has a grain to it so it's not something you could spray on - unless you could somehow make it "run" to duplicate the grain pattern, the longer troughs and valleys in the texture like leather has. 

That SEM product would work on the bumper guards (and be easier than what I've been doing) - but not on the console texture of an Eagle which has a longer grain pattern to it like leather or Naugahyde.

When I repaired the dash pad in my project, "The 69" , I used the SEM product you guys mention. Its expensive and a can doesn't go very far. I used a whole can on one dash. You need at least a 2 or 3 coats. Its the only product I could find. (Pictures in The Project Section)

The dash is not original looking but it is an even texture and looks good. You could not use it for "spot" repair in my opinion.

I used hammered texture paint on a couple of items - small trim parts, and it ended up really nice for spot repairs in those cases where the texture was more like sand paper (SEM describes theirs as being about the same as 60 grit sand paper) and it worked fine - but - it tends to cause even a flat or semi-flat sprayed over it to appear glossy so it takes some finesse to get it right. 
The vinyl and other plastic parts that have more of a leather texture or look to them - those still trying to figure out. The Eagle consoles aren't the texture that the SEM product can produce - the lines are longer, it's not like sand paper but a texture of lines and valleys in the plastic. Hard to describe, will try to get a good close pic of the texture. More like leather or vinyl but on plastic. Not like bumper parts or some other trims that are indeed more like course sandpaper with the tops smoothed off.

AHA - here's a perfect example - you can't spray this -

Bill Check out the Youtube video.  He describes a way to copy and transfer the pattern from vinyl dashes on to vinyl repairs.
