It may be true for Lacquer but who uses that anymore? It absorbs moisture and we know what that means...
It is NOT a good idea if your using epoxy primer unless you really like doing things twice. (Now and when the job fails)
Get it stripped, use a good wax and grease cleaner and get some epoxy on it and your ready for the next step be that next week or next year.



Give me ambiguity
or give me something else
