    I am at the point where I am priming my latest project.
    Yesterday I covered it with 1/2 gallon of Feather Fill primer that I had on hand (about 2 years old)
    It was still slightly tacky and was impossible to sand 24 hours later. This has never happened to me before with Featherfill.
    I stripped it all off with acetone and lacquer thinner.
    I am thinking of using a fresh gallon of Slick Sand and starting over.
    The primer on the car was not affected by the lacquer thinner so I am thinking it is some sort of catalyzed primer.
    I am painting the car with some Centari factory pack that I have had for quite a while.
    I also have some left over Fill and Sand from Dupont that I might use.
    Any ideas on what went wrong with the Feather Fill ?
    Thank you.

  2. Old hardeners
    There's an expiration date on all of this stuff.
    If Beyond the date, use at your own risk.

    Did you use the correct amount of hardener? Did it freeze in the garage? I've used the product and have great luck with it. I do notice that if I get a stone chip it usually breaks at that layer. Maybe try some fresh material. If you think that you are going over epoxy primer you really should scuff the surface.....but maybe you already did that.

    I bought the gallon of Feather Fill a couple of years ago for some front fendersaand only used half.
    I just bought a gallon of Slick Sand today to see if that works better.
    I never had a problem with Feather Fill before.
    I looked at the tubes of MEK and there is no date on them.
    How long is it good for ?
    Thank you.

  5. There is a 6 digit number stamped into the crimp end of the tube. The first number is the year of manufacture and the second two are the month. All hardeners degrade over time and become less potent so more is required to achieve the same chemical reaction. MEKP degrades even faster than cream style hardeners especially if they are exposed to any UV. Hardeners have a maximum of about 18 months of life from the time they are made so two years is well past a useable time frame.

  6. Old Hardener, old product in general, froze at some point, improper mixing..all could be a cause

    The tubes that came with the gallon I just bought have 706071 on the crimped end.

    Can you buy fresh MEK at the paint store ?
     
  10. You can. The ones you got were from June of 2017 so should be fine.

    Thank you for the help.
    I will be trying again tomorrow.
     
  12. You're welcome. The primer should have a code on the bottom of the can as well and should follow about the same timelines although it won't degrade quite as quickly as the hardener.

    I bought a bottle of glaze (shelf life of 18 months) from a local paint supplier. I went to use it about 4-months later and it was thick, like putty. Turns out it was over 5-years old. I took it back and the counter man shrugged and said "It happens" !
