This is the 1/72 Hobbycraft Cf105 Arrow, I started this project a while ago and it has been on and off the shelf of doom a few times. The last time it was consigned to the shelf of doom was because I used Humbrol Clear satin varnish which dried white and powdery. At the time I didn't know how to deal with this but I was lucky that the powdery finish rubbed off most of the surface but was still evident on the red wing tips. With the aircraft being predominantly white I gave it a couple of coats of Vallejo satin varnish and it all but eliminated the Humbrol varnish on the red wing tips. Project rescued.
