Owning your own home is the American Dream.  And over the years many homeowners have realized it. 

However, there is a whole lot of cost and maintenance that can go into your home, from the mortage to maintaining the garage, the air conditioning, the furnace room, the roof, the basement to many rooms through out, and especially your bathroom.  So when a crack occurs in your porcelain or acylic bathtup either have a phone book handy to call a professional or Do it yourself.

Here is a link to a professionals recipe ironically on www.doityourself.com that I thought was well written.  I think this will give you some good direction on how to fix the crack.

And one more reason to have  a Preval Spray Gun around the tool box. http://forum.doityourself.com/designing-kitchens-bathrooms/32923-acrylic-bathtub-crack.html
