Troubleshooting
Paint is not adhering well
Ensure the surface was properly prepared, clean, dry, and free from dust or contaminants before application. Verify that the correct primer (Part 1 of the system) was used and allowed adequate drying time.
Undercoat is cracking or peeling
This may indicate insufficient flexibility, possibly due to improper application temperature or an incompatible topcoat. Ensure two coats of undercoat were applied and that the correct Weathershield High Gloss topcoat (Part 3) is used.
Surface appears uneven after drying
Ensure even application of the undercoat. If brush marks are visible, try applying with lighter, more even strokes. Ensure adequate drying time between coats.
Product is too thick to apply
Stir thoroughly before use. If storage conditions were too cold, allow the paint to return to room temperature. This product is solvent-based and not designed for thinning.
