Big_Jon Posted June 12, 2008 Share Posted June 12, 2008 Hi, Was just wondering what the consensus was about treating the old white powder problem (without replacing the panel). I was just going to grind it clean and etch prime - is it worth priming before filling? (I seem to read all sorts of approaches). Any good cleaners out there for removing the corrosion? Also, has anybody tried the por-15 approach of cleaning, etching and painting (you can then use special filler on top of tacky por15). I have taken this approach on rusty bulkhead and its lasted well. Any wisdom out there greatly appreciated. Jon Quote Link to comment Share on other sites More sharing options...
paintman Posted June 12, 2008 Share Posted June 12, 2008 Thoroughly sand/scrape the affected area to bright metal & IMMEDIATELY spray with etch primer. U-pol's ACID 8 in aerosol is fine. Then fill & paint as normal. Quote Link to comment Share on other sites More sharing options...
