chucky Posted July 16, 2003 Share Posted July 16, 2003 I started to disasemble my zx this week, and I have a ton of undercoating to remove. what works the best? are there any solvents or strippers that work, or do I have to grind it off. I heard that you can use dry ice and chip it off. Quote Link to comment Share on other sites More sharing options...
Drax240z Posted July 16, 2003 Share Posted July 16, 2003 Dry ice may work. A powerful heat gun and a putty knife works pretty darn well too. Quote Link to comment Share on other sites More sharing options...
Guest cbrunberg Posted July 16, 2003 Share Posted July 16, 2003 The heat gun and scraper are good for the bulk. Grinding tends to schmir it all over and thin the base metal. A wire wheel on a grinder isn't bad for after the scraping. a small hopper-gun sand blaster is what I use. They are about $30 in tool catalogs. Sometimes Brake clean or acetone or xylene will work but you have to test it on your particular undercoating. When relacing it NAPA has a reasonable house brand in arisol cans or eastwood supply sells Shootz brand you can spray with a compressor and their gun (not expensive).

PETEW Posted July 17, 2003 Share Posted July 17, 2003 What worked for me was a scaler. It took off the undercoating with ease. If you have a compressor it has got to be one of the best ways to do it. Quote Link to comment Share on other sites More sharing options...

drunkenmaster Posted July 20, 2003 Share Posted July 20, 2003 check my website out, I am doing this at the moment and it is very easy, just time consuming. http://www.angelfire.com/hi3/hiper/260Z.html I am using an anglegrinder and wire wheel and it saves messing around with chemicals and scrapers etc etc Quote Link to comment Share on other sites More sharing options...
drunkenmaster Posted July 21, 2003 Share Posted July 21, 2003 Thanks, I am on my second wheel now and I think it should see me through, if not a maximum of 3 will be used as I am, well over half way now. They are only $25AUD each so it not a huge issue, probably converts to around $13US. The only problem I have which you hit on the head is patience, or perhaps endurance. Lying on my back holding power tools above me gets tiring and frustrating and as such it has taken me much longer than it should. I would say if you had a rotisserie (and the more comfortable working condition it provides) it could be done in a matter of 2-3 days. Need to stock up on my POR-15 supplies soon, not going to be cheap! Quote Link to comment Share on other sites More sharing options...
Guest Your Car is Slow Posted July 21, 2003 Share Posted July 21, 2003 Just out of curiosity....how bad IS the metal under the original undercoating starting to rust on the average? Meaning..if it was left there (given that its not cracking and peeling away)...is it still rusting underneath?? Quote Link to comment Share on other sites More sharing options...
drunkenmaster Posted July 21, 2003 Share Posted July 21, 2003 DM' date=' Not to mention all the debris that will fall on your face, into your armpits and into your shirt if you're not suited up well and have a respirator and enclosed goggles!!! That's why we're lucky enough to have a rotisserie at work. But think of the workout you get to keep you in shape - right?!! RacerX[/quote'] hehe, you feel my pain. My clothing items has slowly evolved over the sessions from an old tracksuit, paper face mask and goggles to the current trade jumpsuit, hair bandana, filtered respirator mask, goggles, face sheild and ear muffs. Takes a bit of scrubbing to get it off exposed skin but it looks impressive to others when you come inside the house As for rust underneat the factory undercoat I have found none other that the passenger frame rail which has previously been repaired by another owner. I guess I am sort of wasting my time but i think it is worth it for piece of mind before pumping big dollars and horse power through a 30 year old body. Actually if any of you get a chance I wouldnt mind opinions on the quality of the rust repairs done to my car, both the sectioned frame rail and the floor/firewall seam.

Guest Your Car is Slow Posted July 21, 2003 Share Posted July 21, 2003 Ah..so as long as the factory undercoating is in good condition without cracks or obvious damage..then chances are the metal underneath is fine? I know I have some areas to fix....but going through the nightmare to strip the whole car is a bit much if im just going to add undercoating again Im going the sandblaster route..im lazy Quote Link to comment Share on other sites More sharing options...
