PLA Impregnation

Tried to search for a discussion on this, but couldn't find anything. Anyway, I want to impregnate my 3D printed PLA part with resin/epoxy material to reduce/eliminate porosity but don't know what to choose. I tried doing some research but was only able to find material impregnation for ABS. Any help would be greatly appreciated, thanks.

I'm not familiar with impregnation but isn't the target material supposed to be kinda porous for that to work ?

You can slap resin on the surface with a scraper and smooth the surface for sure though.
