Lemon Pledge as Sunscreen

In Infinite Jest (a work of fiction, I know), Lemon Pledge is repeatedly mentioned as an excellent sunscreen…

Does Lemon Pledge block UV rays? Has it ever been used as a sunscreen?

The MSDS for Lemon Pledge says this about skin contact:
SKIN:FLUSH W/COPIOUS AMOUNTS OF WATER. CALL MD
(FP N).
