Sealing Dream Gas Tank

Looking for advice on whether or not I should get my 1969 Honda Dream gas tank sealed. I have cleaned the tank initially using electrolysis which seemed to have worked really well. Then I placed the bolts in the tank and rolled in my dryer which removed even more rust, and then flushed and shaked until the water ran clear. The tank does not appear to have any leaks, and the tank is a clean as I can get it. I was going to use por 15 myself, but it seems to be somewhat difficult from what I have read. I decided to have it professionally sealed which he wants to charge me $90 (I don't mine paying if this is the best option), but he said he needed to drill a hole in the tank to get the sealant out. I not sure I want him to be drilling holes in my tank. Is it necessary to have the tank lined? Any suggestions would be greatly appreciated.

Not sure why this is so diffucult. I do it large scale at work all the time with integral tanks. just take your time invest in the right barrier material and EXPECT a little mess. If your tank is not leaking than all you need to worry about is the current openings. plug the small vents with ear protection and use speed tape on the fill port and use the petcock opening for your access. You could either use more speed tape or make a cover plate out of scrap and a gasket out of old bike inner tube. You've done the hard leg work already why pay a guy to do the easy part??

If you can get it clean, no need for coating IMHO, ......others will disagree.

The key is to fill it with gas or spray something to prevent flash rust immediately after cleaning.

Keeping good gas in the tank will keep it from rusting further.

Thats true too. Keep it filled and it will stay clean.

+1 on don't seal it and keep it full of gas to displace the air. Air carries water vapor that condenses inside your tank. If you got most of the scale off the bottom and it sure sounds like you did, then rinse it a few times with gas and reinstall it.

Make sure your petcock screen is clean and intact and before you hook up the fuel line, flush some gas through it with the petcock on reserve since this will draw from the bottom of the tank. After your fuel line is connected, I would also take the carb bowl off and flush through the system again.

Next time you change your oil, check/clean the petcock screen and bowl.
