Product reviewsWD40 Specialist Fast Release Penetrant 400ml

WD 40 Penatrating spray

I bought this item for to help me with my chainsaw repairs.
so far it has been a great help in releasing rusty and corroded exhaust silencer bolts and nuts.
I even had a seized solid engine in one of the saws,.
I removed the sparkplug and sprayed inside the cylinder head,
and left it for a while to soak in.
Sprayed again and slowly managed to get the engine to turn over.
After repeating two or three times I checked the bore & piston and I found no visible damage or scratches visable.
So I would say that the product is excellent.
THANKS JOHN. Read full review...
