I know your pain when it comes to being stuck on a tricky level. For this one don't use the paint pots too soon. Paint groups of blocks to connect as many cages as possible. Finally try to eliminate columns.
Here is a video of a player passing the level without boosters.

Good luck, I am sure you can do it!
