Keris Madura treated badly

[sukuh]

I recently got this keris Madura, someone "restored" it's blade: he sanded it, repainted it with silver paint ( ) and varnish.
After removing the paint (just that) this was the result; some pamor at the base and some near the tip.
To be so rude, what is your advice: do I have to clean it further or do I have to leave it this way?

thanks Sukuh
