Had the bumper off today and the hole was getting rather big , anyways I know its not the best repair as I should have welded in a new panel but decided shirt term to throw some fibre glass in the back and some filler in the front with the old mesh ect and put krust on it all when at bare metal primed up and here's where I am now
Someone's old repair

Most of the Rot out for repair

Filler and primer on

Will get it painted tomorrow , on a budget at the moment so I'm going to have a go at a rattle can job for now I want to know
I've used halfords cans before and there not great
Are holts any good or should I go to a bodyshop supplier and get some made up there ?
Not sure what qualities are like
