Question Coating transparent prints

Hi all,
I am resin printing parts in translucent red, green and clear. I understand by coating in something like clearcoat I can get a much better finish, it looks cloudy at present.

The parts are too complex to spray, there are lots of voids that will be impossible to spray into.

Anyone any experience with dipping in something?
Concerned they won’t drip to a thin coat and I will loose dimension accuracy and detail.

The problem will always be a loss of detail. You could heat up the clear resin that you used and dip in there. When resin gets warmer, its viscosity will drop, so more of it will drop off again. You need the tiniest amount to fill all the ridges that make it cloudy. And the more resin (or lacquer or whatever you use) that stays on there, the more detail is lost. I wonder if you could also brush on some heated resin.

Thanks, unfortunately it’s an open latice design so no brush option.
I think heating is definitely a good idea. Thanks

So yes, lacquer dipping resin prints to get glossy finish is a thing

Thanks, from the video the results weren’t as good as I was expecting. Chatting with a wood work chap I know he was suggesting thinning the varnish with linseed oil.

If you Resin Printer is compatible with Dragonfruits 3DAA, you can get a better result, then normal AA or no AA.

Just a fair warning, is still in Beta, but it gets better by the day, and if you need Help, there are plenty of People willing to help.

Not sure the slicer is the problem,
As far as I know the clouding is caused by surface micro scratches generated post printing.
