Humbrol Enamel Satin Cote -STILL Sticky

[bertie]

Have waited 24 hours for the Satin Enamel to dry over Matt Enamel and I found the surface still sticky and also the matt enamel started to bubble(only on one small area). I have always thinned my enamels with all purpose enamel thinners and this hasn't happened before.

I tried gently sanding the affected area but it won't sand off cleanly.

Has anyone experienced this with the new range of Humbrol Satin ,Gloss or Matt coats???

Thanks

Bertie.
