Sealing Old Mag Fuel Tanks?

[bulletpruf]

I have a few old Johnny Red fuel tanks - two piece deals from 110/111S saws - that have the inner coating flaking off. These are magnesium, of course.

Any recommendations on something to use to re-seal them? Or should I just clean off the flaking stuff and run them as-is?

Thanks,

Scott

I think Jay Hansen has been having those powder-coated. I've used Redkote in my Mac 125 fuel tanks and it works pretty well. Saw-King recommended Kreem as another
liquid fuel tank sealant. I've used both Kreem and Redkote and found Redkote easier to work with. Kreem is good but requires that your tank be very clean. If there are any
residues of any kind, Kreem won't stick good.

Used the Red Kote today on one of the tanks. Seems to work really well. It'll be a few more days before I finish rebuilding the saw and fuel it up, but if I have any issues, I'll post here.

Thanks again, JJ.

When you use Red Kote, be sure to allow it to fully cure before you add fuel. Curing time will depend on how much you use but I generally allow 3-5 days depending on the weather. If it is hot in the summer they will go in the attic for a few days, cold in the winter I take them to the basement and leave them over the wood stove.

I did learn recently that acetone will dissolve even fully cured Red Kote if you leave it soaking for a few weeks.

If you have ever dug failed tank liner out of a previously sealed tank you know you don't want to be the next guy.......
