I thought I'd give the engine a little spruce up , I looked in halfords and saw some de-greaser and barrier sprays in a pack , I'm told the barrier stuff is much like WD40 , and as it was pretty clean under the bonnet I didn't see the point in de-greasing it , and I had a can of Wurth in the van (same as WD40 but not as smelly), so I sprayed it over everthing , left it for a minute or so , then wiped it dry with a duster , looks ok I think , what do you lot reckon ?
