Any particular product you use
@KaptinAmerika?
Especially for around the gas cap. I’m having issues with my flush pop up that is painted.
I started using the liner kits from Caswell as they are selling the kits with the Novalac resin.
There certainly may be others out there also
One thing I have learned is one time around with the liner during installation is not enough to cover the tank completely
It generally takes at least two times of putting the resin in, rolling the tank around, dumping it back into the can, thin it slightly, let the tank cure for a couple of hours and repeat so when you buy the kit don't scrimp on the size of the kit. Get one that will cover more than just one tank.
Novalac Resin, it is my understanding, is what the military uses, among others, for lining their aviation fuel tanks so you know it is going to handle gasoline easily.
If relining your own tank and you don't want the paint damaged buy the liquid mask and apply multiple heavy coats then wrap the tank in a stretch wrap type plastic like they use for wrapping pallets before shipping before masking off the rest of the tank with blue or green painters tape. I cannot over stress this step when it comes to protecting the paint from damage. Plus at the end it makes it super easy to just pull all the masking off.
I have been trying to get to a how to video for the gas bung but there just is no time.
Maybe a forum member can assist with a how to.
I buy the novalac resin off EBay in a 32oz volume.
It only has a one year life so buying too much in bulk is a waste.
We may, at some point, offer a little kit but right now I do not have enough help to make up what we already have to make for inventory with other items so it may be a while.
You only need the above plus:
popsicle stick (or other mixing utensil)
a small mixing pot
The smaller the better as we have found that too big a container makes it more difficult to get the mixture correct.
a small paint brush like the kind used for painting model airplanes etc. I buy mine in bulk from craft stores.
heat lamp (needed to make the resin cure in two hours otherwise it takes forever) any halogen light will work
a piece of 60 or 80 grit paper
blue or green painters masking tape
Mask off the paint around the gas bung, use newspaper or other to cover the rest of the tank, so you don't get the resin any where but where you want it.
Put a paper towel down inside the bung to prevent debris from falling into the tank.
Sand the upper area of the bung down about a 1/4" to clean metal
Sand out around the edge of the bung about 1/8" to clean metal
It may require using a razor knife to get any excess paint and body filler off but it is important to get down to clean bare metal so the novalac bites and seals properly.
Wipe with acetone a few times. Once will not get all the contaminates off so do it several times. Each time with a clean side of the rag
Mix the resin per manufacturers directions
Carefully apply the resin to all the areas of the bung you sanded to bare metal
Pay extra attention to the top edge of the bung where the rubber seal makes contact
You want a smooth distortion free ring that the seal can bite into
Put your heat lamp no closer than 12" for two hours
Once cured clean the paint saver and it's rubber seal thoroughly
If the seal is bad get a new one. Do not try to reuse a bad seal
Apply a little petroleum jelly (Vaseline) to the paint savers rubber seal and install
Make sure you mask off the paint with cardboard before using the paint saver tool in case of slippage by the paint saver tool
No cardboard, one slip and your crying in your beer over scratched paint
Use a bar through the paint saver to get it tight and make sure you are applying constant downward pressure on the tool to prevent slippage
Done correctly you do not need sealant on the paint saver or its rubber seal
Done incorrectly and don't come bitching at me because it did not work
We've done it here dozens of times now over the last 2 years and not a single issue and no new bubbled paint
The above procedure also works great if you have removed your paint saver and are using a Harley style cap.
