REFLECTOR: Jeffco spec sheet

[Chris Barber]

I originally used Jeffco and had complete failure in both strakes. It chipped off in small sheets. I had to almost completely rebuild my strakes. I was not flying yet (still not but may be very close). This was a few years ago. I rebuilt with just EZ-84 (I have a five gallon kit of Jeffco if anyone is interested). I put in several test strips of the EZ-84 with the mogas I have been using back then and as of two weeks ago the test strips appeared perfect. Just some data points.

There's a very thin light grey coat.  Kinda looks like primer overspray.  There's numerous scratches in it and quarter sized bare spots at the bottom.  Underneath it is a light olive color, similar to other unpainted areas.

John,

Jeffco is light grey and EZpoxy is dark tan or light brown.

I was thinking a better product was needed.  Sounds like we already had one.  Is there a way I can tell what was used in my tank?

I find it interesting that the spec sheet, under surface preparation, says not to apply over epoxy coatings.... like the inside of a Velocity fuel tank.  I built my tanks prior to Jeffco becoming the thing to do.  I used 4 coats of EZpoxy and no problems 7 years of 100 LL later.  I did not check EZpoxy with mogas but I did test it with denatured alcohol which is ethyl and methyl alcohol plus acetone.  A scrap in a two month soak test showed no physical changes in it's properties that I could detect.

Attached is the spec sheet for the coating I received from A/S when I ordered “Jeffco” about a year ago.
