Aluminum Mast Refinishing

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   The mast on my Columbia 31 is the original 1966 spar and it is painted white, though when that was done I don't know.  Probably 1966! 
I want to refinish the mast and would like to use Perfection 2-part but wonder if I must sand the mast back to bare aluminum to do so.  You suggest a 24-hour test with Thinner No. 9, but I don't see that product in your list of thinners?

Thanks,

	I am not familiar with thinner #9. In the Interlux line we recommend using 2316N. Soak a rag in 2316N place it on the paint. cover the areas in plastic and let it sit on the surface for 12-24 hours. If the paint is soft after the test then it will all need to be removed prior to using Perfection.
