I found an inexpensive clear coat in satin and gloss (haven't seen a semi-gloss yet ). This is a "NON YELLOWING" formula and is cheaper than the Dupli-Color acrylic clear (gloss only) and available just about anywhere.

Krylon ACRYLIC satin and ACRYLIC gloss !!! Once the Christmas bills are taken care of I will investigate the Krylon matte finish and see how/if that will work for a flat clear coat.

Completed a test panel for the preliminary testing. Panel is painted with Krylon gloss white. Half of the panel is clear coated with the satin, the other half with the gloss clear.

Let the panels dry for 24 hours, then poured 15% nitro fuel on the panel and let it sit for 8 hours.

Everything came out perfect. The fuel wiped off with no softening of either the clear coat or the paint.

Now to stick the panel outside for awhile and see if their "non yellowing formula" is truth or hype.
