POR 15 or Cream

I would not use por 15 as I haven't had good luck with it but maybe thats just me. Not sure about the cream either. I haven't heard about it. Here's what I did last year for my model A gas tank.
1. Get a new box of 50 or 100 5/16 by 1 inch bolts. Put them in the tank with some diesel to help loosen the crud and rust. Shake the tank vigorously for 10 -15 minutes or until it looks shiny on the inside. Use a magnet to fish them out. Tedious but it only takes a couple of minutes.
2. Clean up the outside of the tank with sandpaper or other abrasive and fix any rust holes. Jb weld works ok. I would try not to arc, mig or gas weld a tank. Don't like the pyrotechnics.
3. Use Jasco's Metal etch on the inside of the tank to prep for good adhesion when you seal it. Be sure to rinse the inside of tank with water very thoroughly when done and then make sure the tank is absolutely dry inside before applying the sealer.
4. I used Bill Hirsch sealer. Follow the directions and it will turn out nice. 5. Lastly, paint the outside of the tank.

Maybe others will have different ideas but this seemed to work well for me. Good luck. John
