Hi P-51,
I would recommend "ultracote" for the first covering job. It is more forgiving, needs less heat
and can be repositioned many times in case you mess up. I even save used ultra to patch and it still works.
I have used monocote last week to cover a wing area of my ultrastick in neon color and
wasn't thrilled. It needs to be well stretched before you tack it down on the corners and
had to use a heatgun for a long time to get it to shrink good.
ultracote didn't need that much effort.
Make sure you pick colors with good visibility, look at the models at your field and you'll see
what works best. I admit neons don't look good on the ground but is highly visible up in the air.
Have fun, Pat
