Did the oxalic acid dull the deck's gelcoat, Stan (not that you'd notice on MY boat)? I understand that's the warning when treating fixed woodwork.

I purchased Star brite Marine/RV Rust Stain Remover on sale for $8.10 in a marine supply store and was totally pleased with the results. It contains oxalic acid. spray on , let it work for one or two minutes and rinse it off with fresh water and the rust stains and a lot of other stains disappeared. Stan M-15, #177 Carol II
