Garage Lures

Hi everyone, I'm new here and relatively new to lure making. I've been hand-carving lures for about a year now and I am thinking about getting some plastic blanks soon. My big question is what will work for a topcoat that is relatively inexpensive. I have seen Solarez's products and they seem prettt decent, my choices would be between https://www.solarez.com/product/solarez-polyester-gloss-resin/ (gloss, $33/qt) and https://www.solarez.com/product/low-voc-dual-cure-polyester-resin/ (low VOC, $24/qt) the only problem is that shipping is about the same price as the product for me. Another product I was looking at is Varathane Ultimate Polyurethane, would that work? I am currently using Rust-Oleum 2X Clear Gloss spray, but I don't know how that will stand up over time. Just looking for a cheap topcoat. Thank you, -Garage Lures
