How do I turn stain paint into gloss?

[lotsofchooksnducks]

I've just painted my front door - I got a custom colour at B&Q and stupidly went for satin instead of gloss.

It doesn't look right, it looks too Matt.

Is there something I can buy to get a final coat to make the paint seem glossy?

Yes it’s called gloss

Get gloss in the same colour and repaint

Clear varnish over the top?? No idea apart from that.
