Mine is an Ideal, its a tri fold cover. Its still only a few months old but so far no problems except its kinda heavy for the wife to lift... Seems like a pretty good cover. holds the temp pretty well at least when raising the temps. I have used 303 on my boat but currently use a product called nautical ease vinyl conditioner...( I find it less greasy than 303 but conceed that 303 is still a fine product)
