I am removing the fake silkspan from my Goldberg Shoestring wing.  I am sanding it well.  If there is some fake silkspan on the L.E. and T.E. will an iron-on work if that surface is well sanded?

As you are doing, I have recovered old silkspan wings w/ Monocote. But I have also used a product called Cover Grip which is a heat-activated brush-on glue designed to work w/ iron-on coverings. It also helps iron-on covering adhesion on oil-soaked wood areas.

On any suspect oil-soaked areas, I first treat the area w/ K2R cleaner, let dry, then sand the area.

I also prefer the Top Flite Monocoat covering vs other brands on the market. But just my opinion.

So I am trying the transparent Ultracote.  So far so good.  Never mind the ugly frame. 

So, with MonoKote gone besides Ultracote what other film brands are still available and from who?

I've used them all.

Top Flite Monokote is the strongest and heaviest and it takes the most heat and cannot be used on foam.

All the others are lighter and less strong and take lower temperatures and generally can be used on foam.

They all work.  The tradeoff of weight vs strength is for you to decide. 

At this time any film any color is the best you can do.

This plane used several brands of lightweight low temp film over bare foam.
