@Kirimisakana The colour has a strange name "tanzanite dark blue" with code D14 ... had to get it right using a computer program and to mix various colours and quantities to obtain it, of course it has this chameleon effect.
@Kirimisakana But the work needed to clean the previous painting which was sprayed just to be sold in Romania by some turkish workshop in Germany.... and to clean the old insulation to put the new professional insulation, it took 3 weeks of work to do it.
@neutrinoP Good choice, indeed.
