Hey Ranger,
Here are a few thoughts that everyone can consider. Typically, "healthy" playpen covers do not bleed, especially onto "healthy" upholstery. More often than not, color transfer is the result of a cover cleaned incorrectly or upholstery that has lost its top coat; therefore becoming suceptable to mold, color transfer, cracking, etc. Very rarely, we do get a shipment of faulty materials, and we recognize that. Sometimes, customers think they are doing the "right thing" by using a product that makes the upholstery or cover look exceptionally clean in the short term, but the product may be deteriorating the top coat along the way. That's why we recommend a mild detergent, water and a soft brush for cleaning, followed by a protectant like 303. This holds true for the cover as well as upholstery.
If your cover and upholstery are still under warranty, please take the boat to the dealer for inspection so we can determine if the color transfer is the result of faulty materials (covered under warranty) or loss of topcoat due to maintenance. If your upholstery is out of warranty, try a small amount of mineral spirits rubbed gently over the color, followed immediately by the soap and water rinse. Use mineral spirits sparingly, as this will weaken the topcoat.
Thanks and good luck, TB
