Bath sealant keeps deteriorating

[mutley11]

I have a bath tub that I replace the bath seal about once a year as it keeps deteriorating.

What would cause a seal to deteriorate? I used unibond bath sealant.

Is there a better product out there which will stop me having to replace the seal once a year?

Use a Dow Corning product mate - better by miles in every way!
Mapei is a good alternative.
