Ditch the LustreKote all together.
I have decided after a bad run in with LustreKote to never use it again.
I now go to an automotive paint supplier and get spray cans matched perfectly with my covering. Those are pricy but way worth the cost. The primer is 4 bucks a can though. In the end it evens out. That and it is auto paint. I don't get a lot of fuel on my planes so I am not that concerned with fuel resistance, but the clear coat I use is automotive and resists fuel well.
I am pretty sure that the auto primer and Lustrekote are not compatible though.
I just finished my 35% Pilot for my Extra this way. Check it out.
Hope this helps.
