I purchased a 25 x 36 Hinspergers Polar Boat Cover and on the
first installation noticed hundreds of small pinholes.
I reported this to the Seller and was advised this to be
normal and would NOT affect the service.
In each successive year the number of holes increased by
million and the old holes increased in size.
Now thwe holes are allowing rainwater through the cover.
I contacted Hinspergers Poly Industries several times
and received NO REPLY.
I am very disappointed with teh Honspergers Polar Boat Cover.
I seek advice and information re a better quality winter
boat cover.

Not sure John, But I'd never use the crappy Hinspergers Boat Covers
again.

You could post the telephone number here and we could all call and try
to get an answer / refund for you.

What did you pay for the leaking boat cover?
