Yellowing Plastic in bathroom

In our 1977 bathroom the original plastic is yellowed. Can anyone suggest how to get it cleaned OR if there is an approved paint to airbrush over it? Really appreciate it!

Some have used a concoction called retr0brite to brighten yellowed plastics.

I paint the plastics with an automotive paint.

I experimented with retrobrite.... It worked but paint would be definitely easier if you wanted to do in situ....

Plus one on the automotive paint.

Sand the surface with 360 grit paper and spray some activated car paint, and it will last for a long, long time.

Any plastic which has yellowed such as inner end caps, air conditioner covers, refrigerator vents and even the tambour doors used in some Airstreams can be very successfully painted with Krylon Fusion Paint for Plastics. Use the satin finish rather than the glossy.

Now, if you are talking about the plastic sinks, and shower pans, I can't say it will work, as I have never tried it, but all other yellowed plastic surfaces will come out beautifully. Mask things well, be sure to use a large box fan to vent the overspray, and use a mask yourself. Use many thin coats, do not try to spray one heavy one or you will make runs and a mess.

We also used the Krylon Fusion Paint for Plastics after several sandings of varying grit. It made such a huge difference in the look of our bathroom - I am sure you will like it.
Several others have also painted the curved section of header in the front of their trailers (above the gaucho), but ours is not too bad yet, so I am holding off.
Good luck!

For our bathroom fixtures; tub & sink. I used oneof those gel-coat kits from the home improvement stores.

There is a peroxide method that works. I tried it on some parts and they turned out quite well.

I also used Krylon Fusion in my bathroom tub and sink, and the ceiling. Great stuff.

I am skeptical of the durability of Krylon Fusion when used in areas subject to scrubbing, like sinks and tubs.

I have used two-part marine paint instead for bathroom pieces. I used Interlux Perfection. There are other products that are also good.

I would check with one of those guys that go around painting fiberglass bathtubs. I hear that they are reasonable. I have seen them working at big apartment complexes. They are quick.

While I had my tub/ sink out , took it to an auto body shop to be painted. He used a urethane auto paint, looks greAt & durable . For something like a sink & tub, I would not use a spray can type paint.

Do you use the retro bright first or can you just go straight to the auto paint or gel boat paint

For auto paint you clean, scuff, (sand) and paint.

A 360 or 400 grit sand scratch will make the paint stick.

For this application I would not prime, you want to keep the paint film as thin as is practical.
