   *You shouldnt put ammonia containing sealant in latex inners. But otherwise its up to you. This is pretty much all sealants except those from cafe latex AFAIK *
   
   

Very true - nor should you mix different sealants.

Revo is ammonia free and uses a synthetic latex so should be fine in the latex inners in the Corsas.
