Product Information
Full details
The Pro Range Acid Etch Primer is a professional-grade solution engineered for automotive enthusiasts and trade professionals who require a reliable foundation for metal painting projects. Its primary benefit is providing superior adhesion on bare metal surfaces, ensuring that subsequent topcoats bond effectively and resist peeling. However, users should note that as an acid-based product, it requires careful handling and application in a well-ventilated space to ensure safety and optimal curing.

FAQs
Can I apply this over old paint?
No, Acid Etch Primer is intended to etch into bare metal. It should be applied directly to clean, rust-free metal surfaces for the best performance.
Does this product prevent rust?
Yes, it provides an anti-corrosive barrier, but for long-term protection, it must be covered by a high-quality topcoat or paint system.
What is the recommended drying time?
While it is fast-drying, it is best to allow at least 30-60 minutes before applying topcoats, depending on ambient humidity and temperature.
Is this safe for use indoors?
No, this product should only be used in a well-ventilated area or a spray booth due to the fumes generated by the etching components.
What PPE should I wear when using this?
You should wear a respirator, safety goggles, and chemical-resistant gloves to protect against inhalation and skin exposure.
Can I use this on plastic parts?
No, this is specifically formulated for metal surfaces and will not provide the correct adhesion for plastic substrates.
Troubleshooting
Nozzle is clogging during application
Clear the nozzle by removing it and soaking it in thinners, or flip the can upside down and spray until clear.
Primer finish looks patchy or uneven
Ensure you are shaking the can sufficiently for the full two minutes and maintain a consistent distance of 20-30cm from the surface.
Primer is not adhering well
The metal surface likely still has traces of oil or contaminants; strip the surface again and ensure it is surgically clean before reapplying.

Setup, Compatibility & Care
Setup: Before spraying, shake the can vigorously for at least two minutes after the mixing ball rattles. Ensure the ambient temperature is between 15C and 25C for optimal spray performance.
Compatibility: This primer is specifically designed for use on bare metal, including steel and aluminum. It is generally compatible with most standard automotive paint systems, but it is always recommended to perform a test patch on a small area if using non-standard or custom topcoats.
Care: Store the can in a cool, dry place away from direct sunlight. To prevent the nozzle from clogging, invert the can after use and spray for a few seconds until only propellant is released, then wipe the nozzle clean.
