Clear Acrylic Sealer Msds What Can I Use To Give Something I Have Painted With Acrylic Paint A Glossy Finish?

What can I use to give something I have painted with acrylic paint a glossy finish? - clear acrylic sealer msds

I have painted a plaster mold of the belly of Paris, including the joint compound and acrylic paint. Now I want to finish a gloss on them. I have tried high-gloss acrylic sealer, and made a career of color and gloss polyurethane, and did the same. Help?
