The thread on aluminum trailer painting prompted this question. I've
seen a number of Blanik L-13s in the "original" factory finish of bare
aluminum with blue trim stripes. The aluminum is always dull and
mottled. Closer inspection suggests that the material is not the
typical 2024 surface finish and/or is not Alclad. Has anyone been
able to polish one successfully (successful meaning bright and shiny
and stayed that way for some time)?

Each year we take ours to an open weekend to give pleasure flights. We
give it a good wipe over with oil which makes it shine beautifully.
Lasts for weeks afterwards.
