Testing Resin
I have seen several people say they have had good results with sealing the wood with shellac before painting.
I had ok results but I just did a quick spray layer.
Side note are you using V Carve? If so there will probably be a lot of up and down movement as it moves from spot to spot to carve this.
Check out the “material setup” on the toolpaths tab.
This will allow you to change how high it raises the bit to move to a new location.
I usually leave this pretty high to insure it will clear any clamps. But when you are doing a lot of moves reducing this to a much lower number will save you a tone of time.
