Can MEK Be Used to Buff Out Scratches In Cured Epoxy?

[alsg]

My brother in-law built a cedar strip canoe. He tells me that he buffs out surface scratches using a rag soaked in MEK (methyl ethyl ketone). He thinks it works great. I'm concerned it might permanently damage the epxoy and I'm not sure what it might do to the fiberglass below. Any thoughts?

MEK sometimes used to thin eooxy before curing.
Often used as catalyst for vinylester resins used in composite canoes. No it wont hurt the fabric

It WILL hurt your brother
It is toxic to breathe in the fumes. He may say it works great but it requires a respirator
And good ventilation

Alsp known as methyl ethyl ketone death

He does use a respirator.
