I recently did a fiberglass repair on my fiberglass kitchen sink. Now it's ready for paint. So I have a can of Rust-Oleum gloss white. Now it's been awhile but I'm pretty sure I should prime it first. Since we are moving we have some gallon cans of house paint and primers. But I know the Rust-Oleum needs to go over a sanded surface. So my question is what will send better,stick to the fiberglass, and be as glossy as the sink? I have latex flat,satin,semi gloss, and maybe a can of acrylic, and one can of 100% acrylic latex. What is that?
