Paint is fine no peeling or bubbling just want to prevent from ever happening this is why I want to install paint saver caps.
Mask off your tank around the gas bung before starting this procedure.
Trim the paint and body filler back about an 1/8" from the gas bung, if it isn't done already, then clean the bung up really well about a 1/2 inch down inside with sandpaper and out over the edge you trimmed back. Get down to clean shiny metal. Wipe everything out really well with Acetone several times. Use a two part
Novalac resin, the link to the left is what we have been using, to seal down inside the gas bung where you sanded and up over the outer edge and over the paint about 1/8". If your using the paint saver you can go a little further but don't go past the paint saver edge or you'll have exposure of the Novalac. The novalac takes a few hours to set but can be sped up with a heat lamp or a halogen work light.
Once you have sealed the gas bung with the Novalac resin you don't have to worry about using the rubber seal and it actually makes installing the paint saver allot easier. Use a little petroleum jelly on each side of the rubber seal and the paint saver will tighten down nice.
This is also nice if you ever end up having a liner issue because the saver will not be a torment to remove.
Just be cautious when installing the pain savers. Make sure your applying adequate down force as you do not want the paint saver tool slipping off and scratching paint.
Novalac resins are a fairly new breed of epoxies that will withstand permanent immersion in harsh fuels and solvents. Most quality tank liner companies are using them now for fuel tank lining and many high end motorcycle paint shops are using the above procedure to seal gas bung paint edges before sending the tank out.
The above procedure is not something we have done once on a personal ride. This is a procedure we follow now on every BD that comes through our shop that shows any signs of paint saver sealant issues etc.
