Is there a durable clear coat that can be sprayed over a latex paint?
I have almost zero experience with latex paint. Thanks in advance for any input.

Try MLC Aqualente or Valspar Zenith, both waterborne lacquers. Test first. Make sure your latex finish is completely cured....7 to 14 days.

I haven't used waterborne materials and didn't even cross my mind. Thanks. If using waterborne, what about the cv. Project is going in a bathroom and normally I wouldn't use lacquer.

Target 9000 works good, crystal clear (very minute change to your paint color) and being a WB polyurethane, it's pretty tough.
I use to use a lot of Valspar Zenith and although it's a tough WB I'd stay away from it for this type of application...it had a tendency to craze (millions of tiny cracks) even when you let the latex to cure for two weeks.

As a general rule, applying a harder finish over a softer one is a no-no. You're asking for cracking. I can't think of a clearcoat that is softer than latex paint.

Could clear shellac be sprayed over latex?
From contributor Pa
Most shellac has some yellow/amber tint to it. Also, shellac is not a very good choice as a final topcoat, as it's not very durable or resistant to various liquids.
What are you trying to accomplish by clearcoating the latex?
From contributor st
Thanks guys.
I painted some vanities with a latex base that simulates a metallic auto paint finish. It looked very similar while wet, but when it dried the sheen dropped to a more satin finish and I was hoping with a clear coat to bring back some depth and higher sheen.

I have done a similar job for a resturant (black acrylic {Kelly Moore Dura Poxy} splattered and highlighted with a WB gold {M&M paint?} and then top coated with Target 9000) and it came out beautiful...the key to good results is what has been stated prior... let it dry/cure for a week if it's cool before starting and make a sample to test on before finishing the piece.
