In some cases, you can choose to take the Sevylor Quick Release instead. Keep it out of the sun when you're not using it. Watch your inflation levels and adjust accordingly. Give it room by letting a little air out. In many cases, the answer is yes.
Waterline carries a variety of repair kits, suitable for most inflatable problems.
Of course, if the inflatable is riddled with holes or lost a battle with a rodent or squirrel, then you may have to start over. If there is a leak in a seam, then get the seam seal. If there's a small pin prick hole, then the repair patch that came with the item should be sufficient. If you've lost the repair patch, we've got more. If the hole is larger, such as an animal claw, then air seal is the right product.
