    Ceramit is more suited to jewelry applications - but given that you
    are using Colores already - it sounds like 

    1) the walls were not absolutely clean - wash them with a swab dipped
    in acetone or MEK and let dry thoroughly before use - and always
    roughen the surface with a 3M diamond film on a mandrel or wrap it
    around the non - cotton end of the swab and run it around the bezel..
    

    2) your catalyst may have gone bad - another brand also packages
    theirs in a plastic bottle, the trouble being it is the wrong plastic
    (wrong for the application the company chose the bottle probably for
    costs savings over correct type of chemichal resistance at a higher
    price..the same thing happens to pure essential oils (from botanical
    by - products) - they are packed in a blue or amber glass bottle
    then the not - so - brilliant marketers add a plastic drip tip that
    in at least 80% of the selections offered by the major sellers of all
    natural plant, bark, root and gum oils the compounds they contain
    dissolve or at least degrade the plastics over not that long a period
    of time : wrong plastic for those products). 

    3) you are heating the metal - re - read the instructions.none that
    i have ever read instruct anyone to heat or warm or anything but
    prepare the metal by cleaning it before pouring the resin, or
    epoxy.Another thing to keep in mind being in an arid environment is
    the percentage of moisture the brand new,, and not nearing becoming
    outdated product contains.and the percentage of water loss to
    evaporation from simply running an air conditioner with the
    bottle(s) open in the same room can tally. That does not even touch
    on the storage of the containers,, ambient temperature, light
    exposure and all the other factors that affect both parts of the
    product. 

    If you have recently purchased a certain colour - do a test.. using
    the remainder of that colour you are replacing and the fresh
    product..if both pull away from the sides of your bezels then the
    problem is elsewhere.and do the instructions mention curing with a
    heat lamp, or is that something you thought would expedite the
    process.reread the manufacturers direction to re clarify,, in your
    mind, exactly how they tell you to use their product.if you are
    following it to the letter, and the product is relatively new, write
    the manufacturer and explain that you may have received a bad batch,
    or go to the retailer and turn it in for an exchange, or refund and
    try another brand to add colour in that format.Alternatively,
    consider perhaps using glass effetre/enamels.. rer
