Spatt Posted August 1, 2014 Share Posted August 1, 2014 Hi guys... im going to have the car in the air tomorrow while i service it... while im at it im going to try and scrape back some rusty patches and put some zinc primer on to help protect it.. since i haven't really been under the car is there any areas i should pay close attention too that are prone to cause problems later in life? I have not looked into wax oils and sealing the underside of my car because i think it'll quite expensive? I guess the rusty areas have to be treated some how first anyway?

KyleR Posted August 1, 2014 Share Posted August 1, 2014 (edited) I'd pay attention to the various cross braces and the 2 brackets behind the rear wheels that the plastics attach to. Edited August 1, 2014 by KyleR Quote Link to comment Share on other sites More sharing options...
Ewen@Clark Motorsport Posted August 1, 2014 Share Posted August 1, 2014 You're right in saying rusty parts need to be treated first, just spraying over them with underseal is fairly pointless. If you treat them first with a good rust converter, I have found Blit Hamber products to be good for that http://www.bilthamber.com/corrosion-treatments. Then for sealing the metal POR-15 is excellent. Dinitrol so a really good cavity wax for the box sections and hidden areas and I have found Terrotex HV350 good for converting steel suspension parts. Its not expensive if you do it yourself just time consuming to do properly but very worthwhile as no 350Z came with proper protection, UK or Import. For the cavity wax you will need an air compressor and underseal gun, some good products on here http://www.rust.co.uk/ 2 Quote Link to comment Share on other sites More sharing options...

Assume this is just the difference in products though..... I only have axle stands, I was looking at doing under the wheel arches first and then working from there........ But I will be taking it off the road now every Winter as I don't want the nasty salt to kill my 350Z Quote Link to comment Share on other sites More sharing options...
HiddenWomble Posted October 30, 2015 Share Posted October 30, 2015 (edited) would you guys rate rust.co.uk as a good place to get a full rust treatment? i live near the coast and drive up and down the salted motorways so i'd like to get some protection on her soon. edit: i don't mean buying their products but paying for them to do the work Edited October 30, 2015 by HiddenWomble Quote Link to comment Share on other sites More sharing options...
Dynamic Turtle Posted October 30, 2015 Share Posted October 30, 2015 Is the 2014+ 370 better on the natural rust prevention or is it also typically Japanese on that front? Quote Link to comment Share on other sites More sharing options...
