Some important notes on rust converter:
- Always make sure to read the label.
- Apply product when the temperature is above 50 deg F.

- Only use oil-based paint on top coating and not latex paint.

Step 3: Apply a rust converter with the brush on the smaller areas and a roller on larger surfaces.
Step 4: Let it dry for 20minutes but it takes 24 hours to cure. Application for second coating will ensure proper rust conversion.
Step 5: Clean the rust converter from application equipment by using soap and water.
