Propspeed Etching Primer Base & Hardener is a 2-component system providing protection against corrosion & increasing the adhesive property of subsequent coats. It bonds tenaciously to non-ferrous metals like aluminum, brass, and bronze. For maximum adhesion, pre-treat metal with Propprep metal conditioner before applying Etching Primer. Includes Primer Base & Hardener only.

When applied properly, the Propspeed system has excellent adhesion to keep underwater metal components clean and corrosion-free for up to 2 years. It's also safe for marine life because its silicone-based formula contains no biocides.
Mixing Tip: Propspeed Paint Mixing Wheels (sold separately) ensure thorough and easy mixing of the Propspeed Etching Primer Base and Hardener components prior to application. Be sure to stir thoroughly to remove all the solids at the bottom of the Etching Primer Base container before adding in the Etching Primer Hardener and mixing completely. Mixing thoroughly prevents inconsistencies and premature hardening, while increasing the longevity of the final Propspeed coating system.
IMPORTANT: Proper timing of the application for each component in the Propspeed system is critical for maximum adhesion, efficacy, and longevity of the cured Propspeed coating. For best results, read all instructions and watch the videos before applying. It's also recommended to have a second person to help.

Propspeed Application: 5 Easy Steps
Be sure that you read and understand the information in the SDS and TDS documents for each of the products in the Propspeed sytem before starting the application process.
Etching Primer: Contains solvents. Do not expose containers to open flame or high temperature heating equipment. It is recommended that a barrier cream or gloves be used for hands, and that when spraying, eye protection or proper face mask (respirator) be worn. See SDS for further safety information.
