ive tryed thinner and wd 40 nothing touches it its hard as a rock just in one corner on the bottom hey john how goes it

 

[bubbas dad]

not too bad. it's a long shot but I've had some luck using carb and choke cleaning spray on none acl bottles. spray it on and let it set alittle bit something and try to scrape it.

Coke has long been used to free up old rusted engines . . . perhaps try it overnight.
