Re: Gas Tank Sealer Recommendations.
i use Kreem. the kit comes with a metal etching tank prep, tank cleaner, and the coating.
one kit has done 4 tanks so far, and there's still enough for at least one more.
i think with any sealer, you'll have to remove the old stuff first.
haven't had any leaks yet.
it's about 30 bucks a kit, and it's available at most motorcycle shops, ebay, etc...
