FAQs
Can I apply this over rust?
No. You must remove all loose rust and treat the metal before priming to prevent further corrosion under the paint.
Does this primer need to be sanded?
Yes. For a professional finish, you should wet or dry sand the primed area with fine-grit sandpaper until smooth before applying your topcoat.
How many coats should I apply?
Two to three light to medium coats are usually sufficient. Allow the recommended flash time between each coat for the best build.
Is this primer compatible with all topcoats?
It is compatible with most automotive paints, but always test on a small area or a scrap piece if you are unsure about chemical compatibility with your specific topcoat.
Can I use this on plastic bumpers?
Yes, provided the plastic has been cleaned and prepared with a plastic adhesion promoter first.
Troubleshooting
Nozzle clogging or uneven spray pattern
Invert the can and spray briefly to clear the nozzle. If it remains clogged, remove the nozzle and soak it in paint thinner or replace it.
Primer running or dripping
Apply thinner, 'mist' coats rather than one heavy, wet coat. Allow sufficient flash-off time between coats.
Poor adhesion to surface
Ensure the surface was thoroughly cleaned with a degreaser and properly sanded with the correct grit to provide a mechanical key for the paint.

Setup, Compatibility & Care
Before use, ensure the can is at room temperature and shake it vigorously for at least two minutes to ensure the pigment and fillers are properly mixed. Always work in a well-ventilated area, preferably outdoors or in a ventilated workshop, and wear an appropriate respirator. Keep the nozzle clean by turning the can upside down and spraying for a few seconds after each use to clear the valve. Store in a cool, dry place away from direct sunlight or extreme temperatures to maintain the shelf life of the aerosol propellant.
