The Netcore fender covers are nice, and offer what I'm asking for, but are ridiculously expensive. It seems other than those all I can find are fender covers that are either all soft (meaning brake fluid can soak through) or all vinyl (meaning your paint can get scratched). Anybody know of a brand that is soft on one side, impervious on the other, and doesn't fall off, without costing over $100 for a cover?

 

I have a hard outer shell, but a soft gooey inside, can I be your fender cover?

 

I'd rather you be my mattress cover.
