    Is anyone else having a hard time finding Interlux Perfection? I've got my boat painted in Snow White and see it out of stock at all of my usual vendors. I did a search and found that there is an issue with Interlux getting the chemicals it needs to manufacture the paint and catalyst.

    I need to do a little touch up and I'm wondering if any of you have used Awlcat 3 (mixed at a 2:1 ratio) with Perfection? I have some of the Perfection base (that stuff never goes bad) but my catalyst has kicked off in the can and is useless.

    The finished product doesn't need to come out exactly like the Perfection, I'm not painting large areas, just doing some touch up.

    Hopefully as time goes on things will get better.

    Regards,

    MIA,
    Pending any response here, I'd call Interlux.

    I don't have experience in that specific combination.

    But do have many years of spraying many brands of catalyzed polyurethane.

    It is always best to use the specified catalyst. They are similar enough to usually work off brand. There might be a few issues.
    -increased chance of fisheye or alligatoring.
    -unpredictable drying/ curing/ pot life -times
    -color shift
    -gloss shift
    -viscosity/flow/leveling issues

    I suggest a test drive before mixing up a large batch.

    Good luck

    Blueknarr’s advice on test batch is very important!
    I do small test batches even on products that are familiar to me, especially when one or more components has been on the shelf for a while.
