Is this a DIY gas tank coating?

I've never before seen this in a gas tank. My guess is someone tried to seal a leak in the gas tank by using a liquid sealant.

maybe as important. did it work?

When I drained the old bar oil from the saw it had a 'gas' smell. I'm not sure if it contained fuel mix, was just old, or had been thinned with something. It doesn't matter now as I'm parting out the saw. I'll probably test it just to know.

Thanks for the link. Does anyone know if Bluelightening tank sealant works?

As my cousins from the Fox Valley in WI (Shiocton, Fremont, Zittau area) would say, "Check out my new minibike-EH!"

Haven't seen one of those running since the late 70's!

I did something similar with an old '74 Honda CB360. I kept having to rebuild the carbs every half-tank of gas & finally just paid a radiator shop to seal the tank - I was 19 and didn't have the sense to do that first thing...

Chris, I'm no expert on manufacturing practice, but this appears to be someone's misguided effort to perhaps cure a tank leak. If the factory was doing something like this, I believe it would not have extended beyond the inner tank. Do you agree? I don't believe this would have solved the problem if it was a DIY. The tank is sealed by the gasket. Some RTV sealant filmed over the gasket will help, but coating the tank probably wouldn't. Hope this helps. Happy sawing.:msp_smile

I now have a SL11A that also has a treated ??? gas tank, it looks much more professional than the SL-4. I asked about this in the Remington sticky/thread.

Chris, do you have a photo of the SL11A as well? I collect older Remingtons and have never seen anything like the previous photos. I suppose this could have been one of the "next best thing" fads to prevent gas tank leaks or fuel breakdown?? Don't really know. Would like to see what the SL11A tank looks like though. Thanks.
