Bellicose Posted August 13, 2016 Share Posted August 13, 2016 Odd question coming from me as I should know, being a car painter and all LOL. Need to strip the inside of rear guard on the gadabout. The metal is thin so blasting is out. Lots of crusty surface rust so paint stripper is out. The guard is 'deep' so sanding' with my fat hands is out. Soda blast is out because we only have one guy here that does it and he knows he's got the market cornered and prices accordingly. Has anyone had any luck with any other 'system'? cheeRS.

Nominal Posted August 14, 2016 Share Posted August 14, 2016 I've had a Morrie guard dip stripped. Not sure if there is anyone who does that in your area. Quote Link to comment Share on other sites More sharing options...
Bellicose Posted August 14, 2016 Author Share Posted August 14, 2016 Think the closest one is Rotorua. Love living in taranaki but it's times like this I miss living in a place that has lots of industry like Auckland. Quote Link to comment Share on other sites More sharing options...
Transom Posted August 14, 2016 Share Posted August 14, 2016 Most places that do powder coating have a dip strip tank? Surely one of those in the naki? 1 Quote Link to comment Share on other sites More sharing options...
Bellicose Posted August 14, 2016 Author Share Posted August 14, 2016 That's a thought. Gotta couple down here. Will investigate tomorrow. Quote Link to comment Share on other sites More sharing options...
Frosty Posted August 14, 2016 Share Posted August 14, 2016 Get one of those cheep sand blaster kits from TardMe or Super Cheep and use Rice as the blasting media. Worked for me and they run of a normal Air Compressor, needs a reasonable amount of CFM even my Hinden couldn't keep up at times. Quote Link to comment Share on other sites More sharing options...
tortron Posted August 14, 2016 Share Posted August 14, 2016 Use electrolysis, that usually knocks the paint off Quote Link to comment Share on other sites More sharing options...
Bellicose Posted August 14, 2016 Author Share Posted August 14, 2016 Thought about that but the amount of air required is the down side. My 15cfm 145 litre tank compressor will still struggle. And at the end of the day I'd rather pay someone to do a 15 minute job that would take me most of the day waiting for compressor to 'catch up'.

Mr Vapour Posted August 14, 2016 Share Posted August 14, 2016 Bicarb is super cheap from a pool supply place. Simple soda blasters are easy to make. 1 Quote Link to comment Share on other sites More sharing options...
Bellicose Posted August 14, 2016 Author Share Posted August 14, 2016 Looks like 'electrolysis' will be the way to blow myself up......I mean get the job done. Very simple to set up but pretty wild what it does. It splits the water atoms into separate oxygen and hydrogen atoms. So no ciggies for me while that's going on in the shed LOL Quote Link to comment Share on other sites More sharing options...

So no ciggies for me while that's going on in the shed LOL Yup if ya can fit the whole part into ya solution then its a bloody magic process!Cheap too! If it's really rusty then you may want to pull ya sacrificial bit out and scrap/file it clean a few times. Make sure you get ya anode and cathode round the right way LOL. It won't remove paint tho (atleast from my experience) The water needs to contact the steel under the paint- if the paint is any good then this won't happen. Bin-in sells washing soda very cheaply. You want Sodium carbonate (washing soda) NOT Sodium Bicarbonate (baking powder) For paint use a waterblaster fitted with a sand blaster head. Never used one myself but I hear the results are great and there is no panel warping- the water must cushion the impacts or something. SCA sells the heads. This is from my experience fooling round. If it's wrong plz correct me (for my own good).. Otherwise- hopefully it sends this guy down the right track. (Edit) had a look online. It seems some people have had success with it for paint removal. Maybe some paints are affected more than others? I will try this again!

tortron Posted August 15, 2016 Share Posted August 15, 2016 Use lye with the electrolysis. It's more aggressive and does the paint too 1 Quote Link to comment Share on other sites More sharing options...

bathcollector Posted August 18, 2016 Share Posted August 18, 2016 Molasses and water mix will take care of the rust, paint stripper what is left of the paint. Quote Link to comment Share on other sites More sharing options...
