Three years have now passed since I repaired my tank using fiberglass on the outside, then a complete clean out , etch,
and coated the inside with the three part Moss kit. I also
installed an inline glass bowl fuel filter before the 1st carb.
No problems with trash or blockage at all. No trouble with leaks or any gas smell in the boot ever since. The only substance that will dissolve the the white coating from Moss is M.E.K. which cannot ever be put into gasoline in the future. It would eat through fiberglass fuel tanks which are in wide use in power boats.
If the tank is properly cleaned and etched before the application of the white coating, then that coating should not come loose. An experienced radiator shop that also repairs gas tanks should be able to do the job right. Gas tanks have been reconditioned by radiator shops since their have been gas tanks and radiator shops.
As always, others opinions may vary.
