Gas Tank sealing with POR 15 standard tank seal

Many thanks to Jeff G 78 and postings by others for help with this. I noticed the instructions on the standard tank seal can called for thoroughly stirring the tank seal which I thought I had done but when I poured the seal in the tank there were a few lumps. If you look closely at the flat surface on the right (tank baffle) in the completed picture below you can see a couple of small lumps likely from lack of stirring. I used a pint and a half which is a half pint more than what POR says you need so it should be fine.

I spilled some tank sealer on the outside of the tank and thereby discovered how durable the POR standard tank sealer is when I started wire wheeling the exterior of the tank in preparation for painting.


Original dirty tank:


After acid cleaning with hydrochloric acid (per the bottle, this is a substitute for muriatic acid commonly used for this):


After marine clean and metal ready:


Completed (pink color from camera light):

    • It only takes 6 years... finally, I can test drive my car 😍    
    • Look at the VTO offerings. I have the wheels in 16x8 +3 (off of a 72 240Z that was parted) and they will fit fine on my 76 280Z. The 73 did not have coilovers.

      Mike, I'm looking for advice.  I have a 78 280z and i would like to put 16x8 inch wheels.  Is this possible and should the offset remain at 0?  I've been trying to get a set of Rewind or banana mags and can't seem to find the right set.  Thanks for any help you can give me.  Mark
    • I agree. We have some great members. @Mike Just remember "Imitation is the sincerest form of flatter". I have a similar yellow and the same bullet mirrors. I love the Rota's on your car although my bumpers will be pure chrome. No strips... It looks great!!!
    • Thanks for the pics, Mike. This site helped me in so many ways. I met people from all over the world and visited a few in New Zealand. The Zed is a unique car. There is actually none like it for the affordable enjoyment. I had one back in '74. Traded it for a 3/4 ton 4X4 Chevy p/u when I moved to the mountains. But I never forgot the excitement and love I had for that first car. In 2005 I bought another one and made it mine with new parts, paint, upholstery, etc. My wife calls it the "acceptable
