Trying to paint interior black but looking for paint that would last for years plz post opinion

Trim paint from an automotive store should be efficient enough. A can of black I think is about 5 bucks

SEM is more expensive but gives the best results. Rustoleum is just as good and considerably cheaper. I am not a fan of the Dupli-Color, fades fast, smells strong, very thin and the trigger is odd...in my opinion. I would go with the Rustoleum. Just make sure you clean whatever you are spraying very well and use multiple coats. If your doing carpet I would recommend the liquid RIT dye, harder procedure but worth it to me. Sprayed carpet, cloth, or fabric do not last very long I'd say a year max.

By the way, this isnt the section for this post, try the tech section.

I used the fusion paint specifically for plastics and it works great no flaking or anything i used it on the hatch rear speaker covers since i couldnt find any in black. i could only find burgundy and blue so i painted a set. that was 3 years ago and they look just as good as they did when i first painted them.

If u want to do it once and do it right,Then use SEM products.
For the adhesion promotor u should use Bulldog.

Once its done u will be very happy with the results
