Yet again , veg oil . Nearly newbie , for the love of god do a search cos Mr storm99 is getting ****ed off and you don't want to **** mr storm99 off , cos he's a fecking nutter !1
Either wait until the shine goes , or hamerite or similar , OR proper job is to prime with PLUMBATE PRIMER , good household paint shop will have it . Worked with a sign writer years age and some of the sign I painted like this are still looking good .
