I've had my GL2275 for ten years. The first year, I got rid of the playpen cover and had custom seat covers made. Each spring, I've wash the covers, hung them on a clothesline to dry, then sprayed them with a water proofing product (303). Instead of spraying them while they're hanging on a line, is there any reason I can't put them on the seats and then spray? It would make waterproofing much simpler. Thanks all....
