Troubleshooting

Primer not adhering properly.

Ensure the surface is properly prepared (clean, dry, and lightly sanded). Allow adequate drying time before applying the undercoat.

Primer appears to be 'crawling' or separating.

Ensure the surface is free of contaminants. Apply a thin, even coat. Avoid over-application.
