My cloth car cover that I bought in '85 from JC Whitney is beginning to dry rot. I have looked all over for a replacement but cant find cloth anymore. I like it because I now only use it for a dust cover (garage kept) and it is fairy light and very soft. I'm not too sure about Polypropylene, seems it may not be soft and too subject to tears? Would like to keep it to $75 or less, just something for a dust cover. I did find one made from taffeta?? Any suggestions?
