Refinish AC undressed fibreglass cover

I recently bought four gallons of the evaporust at advanceautoparts. I used one of the online coupons and knocked a ton off the price. And, if you use one coupon per gallon you can really increase the savings instead of just making one purchase for all four. (I had to buy them at seveeral stores since they ususally only have one gallon at a time at the local store)
