Knowing the fun we have sending paints both flammable AND water based from the UK to just outside the EU and they are for one of our aircraft on check. I strongly suggest you give it to the courier firms and let them sweat it out! We end up having to create Commercial Invoices, Customs Paperwork, Airway Bills and if it's flammable the dreaded dangerous goods paperwork
Nevermind we're transporting it on our own aircraft (a freighter). Made even more frustrating when the same tin is returned a week later not needed and no paperwork done on their side except the airway bill.
Stay clear of the hasle you will heap upon yourself and pay the extra of find the local equivalent of B&Q/Homebase/Focus etc
