Let completely dry for a week or so and Do it All Over again. Hot Tank, quarter car wash, rinse and let dry. Then do it all over a third time. eventually working thru all the layers of crud. Subject 392 block was full of crud up past the casting plugs in the side of the block when first opened up. A DIRTY JOB!! Be prepared to get grimy the first hosing out and the second hozing, and maybe even the third time with the high pressure wash. Eye protection Would Not Be Out Of Order. :-) Seem to recall we spent over a month doing this, it worked for us then. Hopefully the chemical cleaning is as effective today as it was back then. -- Paul Holmgren If you think Space is the Final Frontier, You should see my Garage! ------------------------------------ Posted by: paul <paulholm@xxxxxxxxxxxxx> ------------------------------------ To send a message to this group, send an email to: Chrysler300@xxxxxxxxxxxxxxx To unsubscribe from this group, send an email to bob@xxxxxxxxxxxxx or go to https://groups.yahoo.com/neo/groups/all/manage/edit For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm For archives go to http://www.forwardlook.net/300-archive/search.htm#querylang ------------------------------------ Yahoo Groups Links <*> To visit your group on the web, go to: http://groups.yahoo.com/group/Chrysler300/ <*> Your email settings: Individual Email | Traditional <*> To change settings online go to: http://groups.yahoo.com/group/Chrysler300/join (Yahoo!
