I have a 1985 Chris Craft Scorpion 186. Previous owner left it uncovered and pretty much destroyed interior vinyl panels and seats . To him they were fine but I don't like sitting on cracked up ugly moldy seats. I cleaned vinyl best I could with simple green and splash of bleach and water mixer. Which I have used before no problems. Cleaned up good but still dry and cracked . Now when I keep burgundy color cover over boat , the seats and dry vinyl turn burgundy color in sun prone areas. Like color from cover is being burned into vinyl by sun. If I leave cover off few days color fades away. I am sure its just because interior so bad , or my cleaning mixture on dry vinyl. I will get pic posted of it. Thanks
