I hung tarps and covered everything with plastic sheets, and still had to deal with pretty much everything in the garage being wet. I was disappointed in the results too – I suppose it did remove a lot of dust and soil type dirt, but anything greasy would need a detergent or heat to get rid of it. I used a fairly powerful home-type pressure washer – about 3000 psi and 3gpm. I hoped that a lot of the looser underseal would come off, but only the stuff I could peel off by hand was moved. </p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I did read good things about using dry ice as blast media, but it appears to need a special blaster, and I couldn’t even find one for rent in Houston. From what I saw, it would remove dirt only, or turn up to higher pressure and it would remove underseal. The dry ice would then melt and leave the underside of the car clean and dry with only the removed dirt/underseal on the ground. I suspect this would get very expensive unless you had a source of cheap dry ice.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Cheers</p><p class=MsoNormal>Alistair</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><div style='mso-element:para-border-div;border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal style='border:none;padding:0in'><b>From: </b><a href="mailto:Randall.Reihing@utoledo.edu">Reihing, Randall S.</a><br><b>Sent: </b>Friday, October 28, 2016 8:59 AM<br><b>To: </b><a href="mailto:edwd@ti.com">Fisher, Ed</a>; <a href="mailto:triumphs@autox.team.net">triumphs@autox.team.net</a><br><b>Subject: </b>Re: [TR] Sandblast or not</p></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>We once rented and used a commercial duty heated pressure washer to clean a semi truck, tractor chassis and the big diesel engine. It removed everything but the paint, although it did blast off loose paint flakes. That hot, water-soluble degreaser, under pressure, really did the job. Then we hosed it down with fresh water to remove any degreaser residue, blew out the excess water with compressed air and let it sit until it was dry. Brushes and scrapers helped too where the grime was really thick. </p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>RandallS in Ohio</p><p class=MsoNormal>________________________________________</p><p class=MsoNormal>From: Triumphs [triumphs-bounces@autox.team.net] on behalf of Fisher, Ed [edwd@ti.com]</p><p class=MsoNormal>Sent: Friday, October 28, 2016 6:43 AM</p><p class=MsoNormal>To: triumphs@autox.team.net</p><p class=MsoNormal>Subject: [TR] Sandblast or not</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Sujit</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>In my experience any media that will not strip paint, ie, crushed walnut shells, plastic bead blasting, etc. will simply bounce off of grease and/or old undercoating which is ineffective and messy. Even aggressive stuff like Black Diamond will have a tendency to do the same, and will certainly eat paint when it gets through. If your frame is immovable and you prefer to stay in the garage, Kano Laboratories makes a superior degreaser that can be purchased by the gallon. These are the same folks that make AeroKroil, the best penetrant I've found, ever. Have your tarp or drip pans ready and brush away. I've used old wooden paint paddles and plastic bondo spreaders for removal. It takes time, but may fit your application.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Ed in Dallas</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>** triumphs@autox.team.net **</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Donate: http://www.team.net/donate.html</p><p class=MsoNormal>Archive: http://www.team.net/archive</p><p class=MsoNormal>Forums: http://www.team.net/forums</p><p class=MsoNormal>Unsubscribe/Manage: http://autox.team.net/mailman/options/triumphs/randall.reihing@utoledo.edu</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>** triumphs@autox.team.net **</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Donate: http://www.team.net/donate.html</p><p class=MsoNormal>Archive: http://www.team.net/archive</p><p class=MsoNormal>Forums: http://www.team.net/forums</p><p class=MsoNormal>Unsubscribe/Manage: http://autox.team.net/mailman/options/triumphs/alistair.hewitt@gmail.com</p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
