Merry Christmas to you.
Under the upper cowling on my Tri, there is the remnants of some white
substance which is flaking off, looks something like heavy weight
dandruff. I suspect it was a fireproof protective coating in its past
life. Does anyone have a similar experience ? The Fibreglass underneath
it is in good condition. Is this the remains of a still valid process
or is there a new material that is now used, like fibrefrax for example?
