I'm about to paint a PLA 3D print for the first time, and while there is some advice on what primer to use (an automotive etching plastic primer seems to be it), I've not see anything but hand wavy "add a layer of clear coat" for sealing.

Does anyone have any advice on a matte finish clear coat product that works well, as much so I know I have the right class/type of product?

Also, is there much difference between the products from hobby shops vs hardware stores? I can imagine the hobby ones are at a consistency for painting fine details, but it may also all be the same thing.

Thanks

It’s also important to note that things like rub n buff and metallic paints lose their metallic finish if you use most clear coats on them.

Iirc there’s some kinds of clear coat that are fine, but it’s like one product/brand.
