Well, let's try to restart this here...Last weekend, I spraypainted my right speaker grille with High gloss vinyl/fabric duplicolor spray paint from AZ.



Looks good and pretty right? :)

Fast forward to today. I took off the left speaker grille, and the glovebox door. Maybe today wasn't a good day outside, I don't know. But the end result? ****.

The left speaker grille bubbled up in a small part, and now it looks like hell (the rest of it looks like the right one when I painted it). The glovebox door looks like it has glossy spots all over it. I don't know what happened today, but it just turned out awful.

1) How do I correct the issue with the left speaker grille? It's just all clumped and bubbled in one spot. Would a very fine sandpaper correct this without damaging the rest of the paint?

2) Without having to sand off the entire glovebox door and repaint it, is there anyway I can remove/cover up the glossy spots? It just looks like it's an uneven coat and it's hideous.

I would take pics, but it's dark outside so it probably won't be visible.

I don't know much about painting vinyl, but could a second coat help the glovebox?

as for the left speaker, how big is the bubble?

piercey the pilot >: )

edit: we need an evil smiley!

Here comes some crappy pics. It's dark outside :\

And I applied 4 coats to the glovebox, hoping it'd eventually even out. It did not.

Left speaker:

Glovebox (looks perfectly fine in this pic. You can see the awful spots though as the angle of light changes, but you won't see it in this pic probably):

Are you trying to change the whole interior black? There are a whole lot of things that can affect the paint spray, from tiny amounts of contamination on the surface being painted to the humidity in the air.
They interior paints that I have seen seem to work ok on hard plastic surfaces (such as you speaker grilles & ETC) and poorly on softer materials (such as a padded dash panel)

I thoroughly cleaned the glovebox door and the left speaker grille. I did the same thing to the right speaker grille last week and that turned out perfect. I guess the difference might've been humidity, I don't know. I Just want to even out that speaker grille coating and make the glovebox one not suck so much.

I don't know much about painting but a word of caution:

My friend did the same thing to correct his mismatched interior and within a year most of the paint came off from use... :-\ (Though, he might have just been using regular spray paint, I'm not sure)

This paint doesn't come off so far. I tried scratching the right grille with my fingernails to verify this. Nothing came off, at all, so I have high hopes for this :)

I just want to fix the huge screwups I made today >_>

Good enough for me :D Looks great! Wonderful idea...

Good to hear that the paint isn't coming off. As for fixing what's messed up, I can't think of anything besides sanding it down and redoing it. You might be able to get away with just sanding the sections that are messed up... but that might cause an uneven paint job... :confused:

Any idea what grit sandpaper I should use if I try to sand just the sections?

Bad news: this **** scratches very easily now. Can anyone recommend the proper paint for this? >_>

No one would think of painting the interior or a newer car. However, if you're fixing up an older vehicle, such as a hot rod or muscle car, you may want to paint the interior to jazz it up. You can recolor plastic, vinyl, and leather materials. You can even paint the fabric on the roof and seats if you want to. All you need are some materials and the know-how to paint the interior of your car.

To paint the dashboard of your vehicle, you need to take off as many pieces as possible. These include radio knobs, heater vents, gear shift knobs, ash trays, et cetera. Wash these pieces in warm, soapy water. Then, rinse them off well with clean water. Dry them well. You may need to use a blow dryer to get the water out of cracks, crevices, and other small places.

Then, use a clean rag and the soapy water to wash the rest of the dashboard. You'll need to scrub especially hard if the dashboard has Armor All™ or another type of protectant on it.

Next, rinse the dashboard off well, and dry it off with a clean rag. Before you paint the interior of your car, the areas will need to be completely dry in order for the paint to stick well to it. So, let the dashboard air dry while you apply painter's masking tape to the interior. Painter's masking tape is blue tape that peels off easily after the job is done. That's why it's recommended over regular masking tape. Painter's masking tape won't leave a sticky residue like regular tape can too.

Tape off the areas of the dashboard you don't want to get paint on. This may include the bottom part of the windshield, the radio, gauges, the gear shift, and other chrome, et cetera.

Before you paint hard plastic areas, you'll need to rough it up with a piece of fine sandpaper first. Use an old rag to wipe up the dust the sandpaper creates. Then, you'll need to remove the remainder of the dust with a wet, soapy rag. Rinse the area again and dry it well.
Finally, use a clean rag and some rubbing alcohol to go over the plastic pieces, and the dashboard, (if it's made of plastic), one more time. The rubbing alcohol will remove any residue left from cleaning the area with the soapy water.

Most materials that are difficult to paint start with a primer. You'll want to start painting the interior of your car with a primer too. It will create a surface that paint will stick better to. You can find a good-quality primer at your local auto supply store. Read and follow the manufacturer's directions on the can in order to achieve the best results.

Once the primer is applied and has dried sufficiently, it's finally time to paint the dashboard and the plastic pieces. Use a good-quality paint for the job. And, make sure the paint is suitable for application on plastic materials. As always, read and follow the manufacturer's instructions on the can in order to achieve the best results. Let the plastic pieces dry completely before you reinstall them on the interior of your car. Otherwise, the paint will easily chip off.

Leave your car windows down and allow the paint on the dashboard to dry thoroughly too before you drive the car.

If you want to paint the upholstery seats on the interior of your car, check your auto parts supply store for a special paint made for this purpose. The best upholstery paint will be non-flammable and non-toxic.

Basically, you'll need to use additional painter's masking tape to protect areas you don't want painted. Examples of these include chrome on the seat, adjustment levers, et cetera. You can use old newspapers or brown grocery bags to cover large areas.

Read and follow the instructions on the can in order to achieve the best results.


The above sounds about right. From what I can understand, you didn't use a primer, and that is the main problem... unless you didn't clean the surfaces very well (I'd use a cloth with acetone to remove all traces of grease and dirt... but be careful when using acetone, it may be harmful to plastics and vinyl... so test it on the materials BEFORE you use it). Acetone is very handy to use, especially if it saves you from dismantling the whole car in order to be able to clean parts well enough in soapy water.

Without the primer, you have limited the life of the paint considerably, since it will crack and peel off. As an extra option, you might want to give it clear coat on top of the color. There are some very good clear coats to choose from... just go for one that is recommended for vehicle interiors. Do it right, and you are in your personal heaven. Do it wrong, and you are back in this thread in less than 2 months again.
