Hi Gordon..

...

Have you tried a penetrating oil called "Tri-Flo" on those rusted on bolts?<<

I've not used Tri-Flo, but have used Kroil and several other "wonder rust breakers". Where's the best place to find it?? Is it similiar to Breakfree CLP...a teflon enriched cleaner, lube, penetrator?? Harvey/ Ga M-17 Stargazer #294
