Chappers Posted September 26, 2007 Share Posted September 26, 2007 Well I've been in need of some paint stripping of some of the small parts on my new GMC so having tried the usual paint strippers,I've decided to try Caustic Soda!! 2.5ltrs of caustic and about 30 gallons of water in an old water tank and WoW overnight the 12 layers of paint were gone. This is the best by far I've tried and the cheapest. It's only good on steel parts as it will erode other metals very quick. Just wash off with a hose to remove the Caustic. Here's the way I've done it http://img221.imageshack.us/img221/1317/p1010079bm1.th.jpg[/img] http://img221.imageshack.us/img221/771/p1010080vs6.th.jpg[/img] http://img221.imageshack.us/img221/9035/p1010081xc1.th.jpg[/img] http://img221.imageshack.us/img221/5208/p1010082xf1.th.jpg[/img] Quote Link to comment Share on other sites More sharing options...
sirhc Posted September 26, 2007 Share Posted September 26, 2007 I'm not surprised that works so well. We use Caustic stripping at work to remove coatings from compressor components of aircraft/marine engines and industrial gas turbines.

Tony B Posted September 26, 2007 Share Posted September 26, 2007 Must get bloody hot though. What about fumes. Did it strip the galvanising? Quote Link to comment Share on other sites More sharing options...
Chappers Posted September 27, 2007 Author Share Posted September 27, 2007 Must get bloody hot though. What about fumes. Did it strip the galvanizing? No fumes and It doesn't get hot at all,When you add the caustic it get slightly warm. The panels aren't galvanized but will check with some that are to see the reaction regards Steve Quote Link to comment Share on other sites More sharing options...
Tony B Posted September 27, 2007 Share Posted September 27, 2007 Thanks mate, now all I have to do is find one that will fit a complete 101. :whistle: Quote Link to comment Share on other sites More sharing options...

Tony B Posted September 27, 2007 Share Posted September 27, 2007 I'll need a body bag before I'm finshed. Must have thirty plus coats of paint, even find sand in the desert yellow layer Maybe i should throw a paint stripping party :-D Quote Link to comment Share on other sites More sharing options...
N.O.S. Posted September 27, 2007 Share Posted September 27, 2007 It's only good on steel parts as it will erode other metals very quick. Thinking of 101 stripping, does this mean it is no good for aluminium panels? Quote Link to comment Share on other sites More sharing options...
Tony B Posted September 27, 2007 Share Posted September 27, 2007 You would need to be very cautious. The expert tells me the best way is to go area by area with a yard broom then wash throughly as soon as the paint reacts. Slow but sure. PS always work from roof down. Trouble is catching the drips etc. Quote Link to comment Share on other sites More sharing options...
No Signals Posted September 30, 2007 Share Posted September 30, 2007 Thinking of 101 stripping, does this mean it is no good for aluminium panels? Absolutely would not even try it on ally. It does react, and depending upon the specific alloy it will be 'gone in 60 seconds' to quote a phrase. Ok, not quite that bad but it will erode, or react violently with, it very quickly. Strictly on ferrous. Quote Link to comment Share on other sites More sharing options...
Jack Posted September 30, 2007 Share Posted September 30, 2007 Chapper - looking at the colour of the paint on your images, was this GMC ex Norwegian? Quote Link to comment Share on other sites More sharing options...
Chappers Posted September 30, 2007 Author Share Posted September 30, 2007 Hi Jack ,Yes it was Norwegian ,It had so much paint on it that rubbing it down was a major problem. The Caustic stripped the removed parts over night :-D :-D I've removed the thick cab paint with a blow lamp,which was quite easy to do, If your careful you don't damage the inner panel surfaces. Starting to repaint it today Here's some of the progress http://img220.imageshack.us/img220/2990/p1010078lh5.th.jpg[/img] http://img220.imageshack.us/img220/3710/p1010065at9.th.jpg[/img] http://img220.imageshack.us/img220/83/p1010066cr0.th.jpg[/img] http://img220.imageshack.us/img220/893/p1010070fz5.th.jpg[/img] http://img220.imageshack.us/img220/3436/p1010072si3.th.jpg[/img] Quote Link to comment Share on other sites More sharing options...

I don't want to come over, all friends of the earth, but did the resulting hose down mean that the residue went down the storm sewers? Aren't you supposed to filter that sort of haz-chem?

abn deuce Posted September 30, 2007 Share Posted September 30, 2007 what is the cone shaped object on the instrument cluster just below the oil pressure gauge? home made ashtray perhaps? Quote Link to comment Share on other sites More sharing options...
Chappers Posted September 30, 2007 Author Share Posted September 30, 2007 what is the cone shaped object on the instrument cluster just below the oil pressure gauge? home made ashtray perhaps? Correct, Its a side light without the Inners.Was a nice little extra so I thought I'd leave it be. :-D I don't want to come over, all friends of the earth, but did the resulting hose down mean that the residue went down the storm sewers? Aren't you supposed to filter that sort of haz-chem? Caustic is used as a drain cleaner so no problem with that going down the drain,as for the paint 99% stays in the tub so when I finally get around to cleaning that out ,I'll tip the residue in an old paint tin and skip it.
