Hi,
Most epoxies have a good chemical resistance to petrol. The problem is the ethanol within the petrol that slowly softens and degrades the resins. This is especially the case with some bikes using composite tanks as the ethanol content has increased significantly in recent years meaning tanks that were fine are now causing problems on the bikes.
You need an ethanol resistant tank liner to use on your tank so it can be used with modern fuels. You need to look at specific tank lining phenolnovolac epoxies which are expensive and rare. The only one I’ve hear mentionedis GTS 1750 Tank Sealer which cropped up on the forum once.
