Envirotex used to be the thing for that. Don't know if they still make it but try Hobby Lobby, Michaels, or one of the other craft stores. It's an epoxy type of material that you mix half and half (very well I might add) and pour it over the item. It self levels. Try not to get bubbles when you are mixing but if you do usually blowing on the surface after poring will take care of it. I have an item I did 40 years ago and it looks exactly the same.
This would have been my suggestion. I do many projects with this product. I do start with Modge Podge and I use a soft non-synthetic brush to apply it. When dry, a quick coat of polyurethane and then the Enviroex. BTW, that can also be gently brushed on - doesn't have to be poured - and it will still self level if you act quickly.
