For painting fiberglass doors with General Finishes, consider their Exterior 450 Water-Based Topcoat or Milk Paint, which are designed for exterior use and offer good adhesion and durability.
Here's a more detailed breakdown:
General Finishes Exterior 450 Water-Based Topcoat:
General Finishes recommends this for vertical exterior surfaces like doors, fences, and patio furniture. It's a tintable, low-VOC finish with UV absorbers and mildewcides.
General Finishes Milk Paint:
This is a water-based, highly versatile, and durable acrylic paint that adheres well to both raw and pre-finished wood and fiberglass. General Finishes Design Center recommends layering Milk Paint with Exterior 450 for fiberglass doors.
Other Considerations:
Avoid oil-based paints: Oil-based paints are not recommended for fiberglass doors as they can damage the door.
Gel stains: While General Finishes Gel Stain can be used on fiberglass, it's recommended to seal it with a topcoat like Exterior 450.
Preparation: Ensure the door is clean and properly primed before applying any paint or stain.
Primer: Use a quality primer designed for fiberglass, such as XIM 400 White Primer Sealer Bonder.
Topcoat: If using a stain, use a high-quality, UV-resistant topcoat designed for exterior use.
Exterior 450: General Finishes also recommends their Exterior 450 for use over Gel Stain, allowing the Gel Stain to dry for a minimum of 72 hours before
