I have read on hear about a product called por 15 i think. I have a bit of rust that need attention on the inside, alot of it looks like surface, but would like to treat it all properly.
Could someone explain how to use this por 15, it seems to come in different colours to. There seems to be a prep, remedy and degreaser.
I take it its a rub down, grind, treat the area, fill if necessary, prime then paint.
Anyone who has used this steer me in the right direction and what to buy.
Phil
