I received a Solana Spa two person on December 19 ,2005. This spa has been in my living room ever since, about a month ago the inside shell started to blister and peel around the filter area. I contacted the Solana Spa's, they said that the spa is out of warranty. The ''blisters are cosmetic defect and will not affect the integrity of the spa''. It only looks like ***, this is ''American made''.... I would like to see if anything can be done about this problem and if any body out there has the same problem with spa's.
