ProZac Posted February 15, 2011 Share Posted February 15, 2011 My Mini is caked in it, seriously caked. Its great, because it means it's not rusty, however, I need to remove it. Sent the rear subframe I thought was okay away for blasting, and its come back with lots of holes in it. Not really a part I want to take a chance with, so I'm going to have to clean up the one thats actually come out of the car, thus the removal of all the underseal... Does anyone have an bright ideas to make the job a bit easier? Current plan is to chisel/scrape what I can off, then douse it in petrol and set fire to it.

yorick Posted February 15, 2011 Share Posted February 15, 2011 Soak with diesel or Kero for several days then blast it off with a steam cleaner. Easiest way I've found, at least you won't have to roll the car on it's head to get at it! Oh and it's not very environmentally friendly so choose the place you're going to steam clean it carefully. I use the local Hirepool, they have a cleaning bay and a steam cleaner and quite reasoable. A lot cheaper than taking it of their site for a day hire which is horrendous.

mikuni Posted February 16, 2011 Share Posted February 16, 2011 Don't burn it with fire! Above solution sounds reasonable. Quote Link to comment Share on other sites More sharing options...
JoKer Posted February 16, 2011 Share Posted February 16, 2011 half a hack-saw blade in a sawsall or air chisel GOGGLES are a must Quote Link to comment Share on other sites More sharing options...
danger Posted February 16, 2011 Share Posted February 16, 2011 depends how solid it is. Can freeze it with dry ice from BOC and chip off, try chisel it off as is, or Last time I filled my spray gun with thinners and sprayed over it till it softened then I scraped it off with a paint scraper and sprayed down the left overs till they came off. Used few litres of GP thinners but did the whole underside of the car Quote Link to comment Share on other sites More sharing options...

RUNAMUCK Posted February 17, 2011 Share Posted February 17, 2011 nah, it'd be that horrible british tar based stuff. dry ice will likley make it cold tar under seal. I'd rock with option A. Quote Link to comment Share on other sites More sharing options...
aw11rob Posted February 17, 2011 Share Posted February 17, 2011 if you do try and scrape/chisel it off, use a heat gun. (worst case) Quote Link to comment Share on other sites More sharing options...
