New tin of POR15 has arrived. Ready for when I take bits off under the TA. Give it a nice coat before refitting new parts. Costly stuff, around £60 for this tin.
I have paint brushes. Can't easily clean off POR15 without costly thinners and without making more mess. Cheaper to buy throw away brushed.
You worry about cost paying 60quid lol. Hammerite just as good other suitable paint rust protection out there lol.. Got to keep the advertising people happy.
