I coat the inside of the engine compartment with a mixture of epoxy and Practer 'Namel color.

Then cover seperatly, the bottom - sides - top of the cowl in that order... the usual manner of installing covering.

When covering this area. Cut the piece way oversize. Warm the contact area with the iron while pulling on the edges. Use the excess to grip the covering and stretch. The fuselage must be held down some way while doing this.

Due to the smaller areas, wrinkles are not that much of a problem.

Enjoy,
