I supply Doculam for covering with most of the kits and I’ve worked with it pretty extensively. It is very similar to Monocoat and Ultracoat and it’s the same 1.5 mil “not mm” thickness and weight as Ultracoat Parklite but also is stronger and not as prone to sagging and loosening up as dedicated coverings tend to do.
It can be tinted and painted on the adhesive side and the adhesive still keeps it’s hold. It can also be scuffed and painted on the outside and is a popular base for those that want to cover the plane in tissue for that vintage look without worry about it tearing.

It comes out frosted white from the roll which turns clear once you apply heat to it. I buy it in 500 foot rolls and I also include extra with the kits so the builder can experiment with it on their own. This is the high temperature version so you will want to turn up your heating iron to get it to adhere which makes it heat resistant during the summer or if the plane is left in your car during warm weather.

I buy the specialty paint from Amazon.

A range of other colors are available to choose from. Showing it tinted in yellow with this example.

Showing a faded, opaque pattern, something that you cannot do with dedicated regular covering.

Showing it done up without adding tint.

Make your selection, each section is 25 inches wide and shipping is free for the lower 48 US.
I’ve used this both on the free flight and the smallest 80 gram RC plane here along with the largest model I produce. It can handle even larger planes just as you would be using regular Monocoat or Ultracoat for along with while also maintaining the Ultracoat Parklite weight which is meant for smaller Park Flyer and free flight models. Checked out the Covering guide page for a tutorial upon using it.
