I fixed the wheel shroud on my '86 Vette using a soldering hot air station with matching plastic welding rods. It was cracked in 3 different places. Good pieces to start out with since it's not readily visible, but it was pretty easy to do. I think I've watched every single Polyvance video, it's a great channel!
@@larrybud It was PLA and it was a riding lawnmower plastic tank. The two plastics melted together quite easily. But, it is showing zero signs of failing.
@@jmoneyband13st75 PLA and polypropylene, if that's what is was, are somewhat compatible, however pla degrades over time with gasoline. Keep an eye on it.
No I didn't. I mention Polyvance @ :28 seconds in, and give their URL at 3:40 www.polyvance.com. I'm just gonna assume you can figure out where to get an angle grinder and pads, there are thousands of places online. Good luck! Thanks for watching!
Automotive polyethylene fuel tanks are not just solid polyethylene. There are five layers. Carbon black outer layer that blocks UV. Recycled polyethylene. Admer adhesive. EVOH which is a crucial non-permeable barrier for vapors. More admer adhesive. Then polyethylene. How does this filler act as all the layers and their required purposes? If your tank has a hole I would encourage people to either buy a replacement tank from an authorized dealer or even replace with one from a junkyard.
This is an aftermarket tank used in an off-road vehicle. The repair has held up very well so far with it's limited use. Not sure about the chemistry between layers, but it seems like if the rod is matched to the PE, and you're getting a good fusion between filler and substrate, then it'll seal, which is definitely the case with this one.
Junk yards here punch holes in the tank to drain 😵💫. Mine seeps around where the filler neck fitting is attached to the tank. Epoxy putty worked for awhile, but the streets in the New Orleans area are horrible. I’m going to have to look into this kind of repair (01 olds silhouette with 276k miles).
Depends where you are, and what shipping costs for a new one to arrive, and if you can wait for a new one that might be out of stock, and if you have to use the vehicle in the meantime... alot of farm equipment has polyethylene and polypropylene tanks, maybe those need to be fixed? and maybe they're more expensive than the cost of the equipment to fix it, learning how to repair might mean you NEVER have to worry about downtime with your equipment ever again? I just think it's cool to learn new things and get out of my comfort zone. Thanks for the comment! :)
