sealing damage in lacquer and metal jingasa

[werdna]

Hello,I have a couple of lacquer and metal jingasa with damage to the lacquer surface or the painted surface on metal,so with chips,cracks etc and areas below the lacquer/metal surface which are clearly visible.Visually I have no problem with this but even a small move makes chips fall off,I don't want to repair them but I would like to either spray a clear coating on to them or wrap in something similar to clearfilm.Is this acceptable without reducing the value and if it's acceptable is their a recommended product to use on my jingasa

Hi, I asked a similar question a while ago and Ian Bottomley recommended Paraloid to fix the brittle parts (Thanks, it works fine!):

Hi,ebay has paraloid B72 is this the item,I'm not sure as the ad says its to use on coins and so I don't know if B72 is just a special additive relating to coins.I've looked at possibilities for clear nail varnish but it appears to be only suitable for small areas.I read in a post that conservators use paraloid because it's removable but this isn't really an issue I am concerned about,I want to cover the damage solely for protection and to prevent further chipping

Paraloid b72, and Butvar B76 and B98 are used on the preservation of fossils. Its a plastic that is dissolved in acetone that can be brushed on. It will add a somewhat "glossy" look though.
