Primer, Part 2

Ok, I will be needing to prime some of the tail section soon so I spent some time looking at different primers. I looked at Sherman Williams P60G2, SEM Self Etching Primers and AKZO.  I found a good source for the AKZO primer and instead of the $200+ price that Aircraft Spruce wanted for the stuff, I found it for $150 shipped.  That seemed to be around the same price that I could find a gallon of the SEM primer and I couldn't find much pricing on the Sherman Williams stuff so I went ahead and ordered the 2 Gal kit of the AKZO.  One Gallon of primer and one of activator.  Some of the not so good points about AKZO is that you need to give it 30 minutes between mixing and spraying.  Also with epoxy primers, you don't want to mix up a big batch and then not use it.  I got the 3M Paint Preparation System also so I can mix up little batches and use the liners to either save the left over as I can put it in the freezer to keep for a day or two, or I can use it to just mix up a little and the mess isn't so great that it is a royal PITA to do.  I also looked at the process and instead of using the normal MEK or like, I am going to try PreKote.

The Prep order will be:

  1. Scrub with PreKote and Brush
  2. Scrub with Scotch Brite
  3. Scub again with PreKote and Brush
  4. Wash
  5. Air Dry
  6. Spay with AKZO
I may regret this, but it's time to get off the pot. ;)
