And after trying again, I got the burst looking great and went to seal it with shellac out of a spray can.....
And the new layer melted into the burst and made it blotch really badly
Glad I did a seal coat first! I'll sand back to the seal coat again and try and do the layer over the burst with a gun or the airbrush instead. I think the mist out of the can was too thick. A finer mist laid on with very thin layers for my tie coat before the 2 part clear should work a bit better.
