pw8757 Posted January 29, 2015 Share Posted January 29, 2015 My Defender (1986 90) "repairs" have developed real mission creep as I've found more and more wrong - including electrolytic corrosion to the seat belt mountings - and I've taken the tub off to fettle it. I'm now considering taking the paint off down to the metal and wonder which might be the best way. Is there a method of media blasting that will not attack the metal? Or is the best way a job lot of Nitromors? Thanks in anticipation......... Quote Link to comment Share on other sites More sharing options...
Snagger Posted January 29, 2015 Share Posted January 29, 2015 Walnut shell, soda crystal and ice pellet blasting should be OK. I wouldn't recommend anything harsher. Nitromors will strip paint but will not remove bad corrosion. Quote Link to comment Share on other sites More sharing options...
robertspark Posted January 29, 2015 Share Posted January 29, 2015 Soda is readily available as is the adapter kits but it's one use only stuff and it goes absolutely everywhere but is obviously biodegradable .... So the neighbours can't complain about the dust..... I use this company for blast stuff plus media https://www.btowstore.com/epages/BT3620.mobile/?ObjectPath=/Shops/BT3620 N.A Robson poulton (not sure if link will work) (Never used soda myself, garnet is my chosen media) Quote Link to comment Share on other sites More sharing options...
Snagger Posted January 30, 2015 Share Posted January 30, 2015 The biggest problem is heat build up through the abrasion, so keep the nozzle moving over a wide area, being patient to gradually wear through the paint rather than clean a spot back to bare metal in one go.

pw8757 Posted January 30, 2015 Author Share Posted January 30, 2015 Had a try out with some Nitromors today......seems the most convenient for me - worked well. Thanks for the suggestions. I'll post some pictures of progress! Quote Link to comment Share on other sites More sharing options...
