Remove a rusted bolt with a crayon

[396 SS/RS]

To me it seems a penetrant would wick in there easier. Might have to give that a try some day. If I was trying that, I would be heating the material around the bolt and not the bolt itself. Heat directly on the bolt would cause the bolt to expand.

One would think. I have had way better success with the wax than the penetrant for situations like I described.

Exactly!

by virtue of physics: Capillary Action & Melted Wax (i.e. Melt Viscosity mPa) has a viscosity Less than that of Petroleum products-Oil Or Water. Then the Surface tension also works in Wax's favor.

A Pro Tip from Submarine Maintenance: "If/When Possible, using electric-induction, open-flame, Steam, Heat gun etc methods to apply heat to end opposite the fastener to promote propagation of the Parafin to 'Creep to the Heat' ."

I prefer to use Old Candle throw away from B-Day Cakes

Unless a fastener is recently rusted stuck, I've never had any success with penetrant on long term seized fasteners.

I have a Bolt Buster to break the rust lock. The wax would probably allow the fastener to turn easier.
