RMC Posted February 24, 2014 Share #1 Posted February 24, 2014 Does anyone have suggestions for solving problems I have encountered in trying to seal copper plates on my Vanguard. The saga is described in painful detail in my Vanguard log in kits in progress. Advice/ experience gratefully received. RMC Quote Link to comment Share on other sites More sharing options...
RMC Posted February 24, 2014 Author Share #2 Posted February 24, 2014 Sorry, rather than wading though all of my log, the problems are shown on page 13. Quote Link to comment Share on other sites More sharing options...
Lou van Wijhe Posted February 24, 2014 Share #3 Posted February 24, 2014 Zapon lacquer is often used to protect metal parts from oxidation and tarnishing. I never used it myself but I once read that you have to be careful when applying it with a brush as you might enclose tiny air bubbles. Spraying is better, as Brian C said. Zapon lacquer is very well known and available world-wide, presumably also in Australia. Lou Brian the extraordinaire 1 Quote Link to comment Share on other sites More sharing options...
normanh Posted February 24, 2014 Share #4 Posted February 24, 2014 Let it age naturally, any spray lacquer is very likely to show any poorly covered area in time as it will develop a patina unlike the covered area and it will look patchy, seen this so many times in brass and copper objects however carefully sprayed. Aged looks better in my opinion every time. Norman Quote Norman Current build Trumpeter Arizona 1:200 with White Ensign PE and a Nautilus Wooden Deck.

RMC Posted February 25, 2014 Author Share #5 Posted February 25, 2014 Thank you all for your thoughts. My problem has been not with "normal" aging/tarnishing, but really unsightly streaks and blobs which appear very, very quickly after very thorough cleaning, and which even appears under a coating of polyurethane. I suspect it is a reaction of some kind which, having cleaned off a poly coating twice, now seems to be dissipating. I have never seen anything like this before.
