Fiber Glass Gas Tank Repair Part 2

This is the second video in a series. I was given a motorcycle that is very rare and the parts for it are expensive. I decided to go as cheap a fix as possible. The gastank leaked so I decided to fix it with fiberglass and this video will walk you through it in detail. I hope you enjoy this, please leave questions and comments.

Good videos, but where's Part 3?!

I'm restoring a very rare 50 year-old Italian motorcycle and the bottom of the tank has many rust holes. A few questions:

1. Would carbon fiber, graphite or Kevlar cloth/chopped roving/non-directional fabric perform better than fiberglass?

2. What do you think the likelihood is of water-contaminated gas working its way between the patches and the tank's steel exterior, and rusting?

3. Will the cured fiberglass and resin withstand the engine's heat?

Thanks!

With a tank sealer like the one im going to use from Caswell no water will be able to get betweent he patches and on the outside its pretty much dependant on the prep of the metal and removal of the moisture before painting.

Fiberglass and the resin will withstand alot of heat and doesn't like to burn. It really depends on what you put it on.

BTW carbon fiber will be good Kevlar is a bit overkill unless you want it that strong. Carbon Fiber will give a great look if you use the vacuum system

Well I'm going to use a gasoline poof sealant inside the tank. I'm currently working on getting part 3 done then in part 4 I'll do the sealer inside.

@GalaxyDrifter1 For the inside of the tank I'm using an epoxy sealer that will not dissolve in gasoline from Caswell

great just what i wanted to see , i was going to have the tank brazed repaired but seeing this has me thinking a fibreglass repair would do and save possibly making a mess of the tank with a torch ! .... again thanks for taking the time to show us how its done , all best Greg

You did a great job!

funny part is that underground gas storage tanks are made of fiberglass now. Thank for the video. You saved me tank.

I thought gasoline, will soon disolve the epoxy and start to leak, if you have experience with this work, please let me know, because i have been trying to go for a custom fiberglass tank, but the fiberglass gurus all say that I shouldnt.
