Hi everyone, I am a big Z fan like all of you on here. I'm currently building a 300ZX that I've owned for 15 years now. She is getting a big birthday and hopefully will be ready to run at the end of the year.

that looks like a damn serious project you got going on there.

Thanks. I've been sanding all day doing the old engine bay shave.

What size are the rear rims? And is it going to be running airbags?

Looks like its going to be a very nice car when it's done

Hi there, tears are 24x15" and airbags are installed front and rear.

Just looking at what you have done in the engine bay. If you strip the car back to bare metal especially if it is a large area it needs to have a coat of zinc etch to protect the metal from rusting under the paint or the filler. I am a Panel Beater by trade and have seen cars where this has not been done and 5 - 8 years down the track it will start to show spider web rust marks under the paint. You can actually see this on very old cars that still support the original paint, and the zinc has worn out or been used up. You will see marks in the paint that look like spider webs, its actually rust.

What happens is that the bare metal needs a coating of a sacrificial product. The zinc paint works very much like a zinc block on a boat. You can get away with it if the repair is local, as the products either side will conduct the electrical charge that causes this. But on bigger areas it is a must. Use the right product and you can bog straight over it. If you want to avoid rubbing through when you sand, you give it a few coats of spray filler first.

Oh no do I have to take all the big off now?

I think you should put bigger rear rims on.

Up to you. Spraying an etch over what bear metal you have left will help but in time it will start rusting under the filler will take some years to show.

I know I was going for 26" but they just didn't fit. I'd have to have the tub going through the hatch. But life is all about compromise so 24's it is.

Thanks mate I'll get zinc spray tomorrow. Just the crc stuff ok?

bernjean · Post by **bernjean** » Thu Feb 04, 2016 8:30 pm

No not a can of zinc spray. You need to go to a a car paint supplier and get the proper stuff it is normally two pack. I will pm you tomorrow and advise you of product and where to buy it. This is what I use under filler. You can actually brush this on.
