How to find and use the Cutting Powder on Cayo Perico to weraken El Rubio's guards during the heist finale.
During the Cayo Perico Heist intel gathering phase, you can find and use Cutting Powder, an optional Point of Interest. Contaminating one of the island's water towers with this powder will weaken El Rubio's guards during the heist finale, making them less accurate and slower to detect you.
The cutting powder can be found in one of the three locations, and it spawns randomly. There are two water towers on the island, and you can contaminate either one of these. You do not have to put the powder in both of them.
Cutting Powder Locations
There are three possible locations where you can find the Cayo Perico cutting powder.
Cutting Powder Location 1
The first location is in the middle of the island in a shed where some workers are manufacturing drugs. The box of cutting powder is orange in color and easy to spot as it glows brightly. The box will be next to a trash can.
