Hi [mention]gymwitch[/mention] it was on FB but here is a link to it on ebay, https://www.ebay.co.uk/itm/TANKCURE-KIT-RUST-REMOVER-CLEANER-Fuel-Petrol-Tank-Cure-Restoration/382270153348?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D225114%26meid%3D9fc70210fa064bbc9cc495f74d11bfd6%26pid%3D100970%26rk%3D1%26rkt%3D9%26mehot%3Dpp%26sd%3D382270153348%26itm%3D382270153348%26pmt%3D0%26noa%3D1%26pg%3D2380057&_trksid=p2380057.c100970.m5481&_trkparms=pageci%3A2c99f1ac-b77e-11ea-8139-e6dd0d37eef8%7Cparentrq%3Aef841f9c1720ad397f261141ffed2bd7%7Ciid%3A1 it has got mixed reviews and apparantly does NOT come with instructions, i would advise doing some research on other products first as this seems rather expensive for what it is supposed to do, it might pay in the longrun to send to a specialist and have it professionally done just for that peace of mind
