spunkula Posted April 7, 2003 Share Posted April 7, 2003 I remember reading an article talking about dipping a car body in acid to remove all tar/rust/paint, etc from the frame. I don't remember the article very well but the problems with doing this are its expensive but the results were fantastic? Could some people shed some light on this and what I really want to know is if any of you have done this to your Z. Cheers, Aaron Quote Link to comment Share on other sites More sharing options...
Tim240z Posted April 7, 2003 Share Posted April 7, 2003 I think that the major drawback is then protecting the areas that are inaccessible from rusting again. The only way to be really sure would be to then dip the entire unibody in primer or some type of metal prep so that the areas that can't be painted will be protected again. Otherwise, apart fromt eh expense, it would be a great time saver!! Tim Quote Link to comment Share on other sites More sharing options...

Tim240z Posted April 7, 2003 Share Posted April 7, 2003 OOOH, that looks rough!! Needs a second dip? Tim Quote Link to comment Share on other sites More sharing options...
denny411 Posted April 7, 2003 Share Posted April 7, 2003 That looks like they let it sit out in the rain after it was dipped. Quote Link to comment Share on other sites More sharing options...
CruxGNZ Posted April 7, 2003 Share Posted April 7, 2003 Here is an acid dipped z...I don't know any details about it or the process though. I remember seeing that picture recently, but I thought it was put in a giant oven to cook off everything? !M! Quote Link to comment Share on other sites More sharing options...
inZane 240 Posted April 7, 2003 Share Posted April 7, 2003 Nevermind about the acid part. I guess it was put in a giant oven?

denny411 Posted April 8, 2003 Share Posted April 8, 2003 Another drawback to dipping is getting all traces of acid of of the car and out of the little cracks and crevices. If any residue is left it will cause the new paint to blister and peal, and it`s seldom a good thing when something blisters and peals.

stony Posted April 8, 2003 Share Posted April 8, 2003 I dont remember where i saw it but anywhere that can do it right dips the body in several vats including metal prep and primer. Quote Link to comment Share on other sites More sharing options...
deMideon Posted April 8, 2003 Share Posted April 8, 2003 The 280 I am working on is a prime example of what not to do. It was dipped and not all of the solution was removed and yep it's peeling in places you cant't get to. It really sucks. I was going to get it dipped again and done right but it's just too expensive!

Guest raystorm280z Posted April 9, 2003 Share Posted April 9, 2003 any rough estimates on how much dipping/coating runs? i would expect that the dipping/coating procedure would be a good solution to the peeling, i think i remember the show "car and chrome" doing it to one of their project cars, it looked pretty clean Quote Link to comment Share on other sites More sharing options...
j260z Posted April 9, 2003 Share Posted April 9, 2003 i am cleaning alot of my suspension and drivetrain parts with Hydrochloric Acid (and alot of knowledge, attention and equiptment) before getting them powdercoated and such. the biggest problem is how to rinse off all the acid and protect them before the rust starts, which is almost immediately. if i were going to dip my car i would most certanly request to see the process and make sure that they could coat all the hard to reach places. if i could be certain of the process i would definately get it done.

j260z Posted April 9, 2003 Share Posted April 9, 2003 thanks for the tip. i'll have to pick some up next time i'm at the parts store. Quote Link to comment Share on other sites More sharing options...
Guest cowboy6280 Posted April 23, 2003 Share Posted April 23, 2003 If anyone is interested there is a facility in Atlanta called UnPaint. Not sure what type of chemical they use but I have had parts done. Not any body panels or a whole car but bracket type parts and they come out very clean. From what they told me after they are dipped to be cleaned the parts are then dipped in a nuetralizing solution. I am new to the 280z thing and just purchased a '77 280z project and was thinking of having it dipped. Quote Link to comment Share on other sites More sharing options...
