Reddit reviews J-B Weld 8237 PlasticWeld Plastic Repair Epoxy Putty - 2 oz.

I tested a number of epoxies on plastics, and found JB Weld PlasticWeld to hold the best on the various plastics I tried. There are a variety of types of plastics, and what works on one won't hold another.

Try something like these

It's very important to let it cure for at least a day or two. Even then it wouldn't be very structurally sound. I would recommend swapping the shell, but if you're not experienced it might be something you would have to pay to have done.

Edit: I should probably add that you should try to cover the PCB so you don't get any spillage on it. Tape would do fine.

If qbond doesn't work for you there is also a 2 part molding clay that will stick/mold to anything and then you can filed it down to at least look aesthetically usable. Holds anything from plastic, wood, metal, obviously get the right type for this JB Plastic Weld

Too give you an idea, its held my 8 inch cracked bumper together for 2 years only by applying it to a the surface inside, its held/sealed a crack in my parents basement shower that i used for 2 years before I moved out, and It sealed a radiator leak that constantly sits at whatever the engine coolant temp gets too. Just mold your headphones with it where they fit and they'll never break again, at least not where it was welded.

I know I’ll get some shit for this, but, one time I had a Nissan that had a leaking fuel pump like this and I didn’t have a lot of money. So I cleaned the pump really well and shined a light on it while someone turned on the key and I found the tiny crack that the gas was coming out at.

So I went in my toolbox and found this plastic weld that I had bought previously. I put a coat, let it dry, put another coat and I drove that car for two years after that and never had a problem

I didn’t want to buy a cheaper autozone pump because they don’t last long and an oem pump is a lot of money

This is what I used.

I would use 2 part epoxy putty

Plastic repair putty?

It comes in a lot of different types but here's one:

JB Plastic Weld (Putty)

If you don't want to use caulk, I'd suggest going with something inexpensive that comes in a small size, like this:

http://www.amazon.com/J-B-Weld-8237-PlasticWeld-Plastic/dp/B003S2E4UE/ref=sr_1_9?s=automotive&ie=UTF8&qid=1406699163&sr=1-9&keywords=fiberglass+repair+kit

or even old school JB Weld. I think silicone caulk could work well, but if it doesn't then something that cures hard might give you more satisfactory results.

You could try some epoxy putty, e.g. https://www.amazon.com/J-B-Weld-8237-PlasticWeld-Plastic/dp/B003S2E4UE/

Might be easier if you can get the metal inserts (nuts) out of the hinge, then you can put the putty in/around the damaged holes in the casing and screw the inserts into that, you could put the screws in the inserts while scrweing them in, to avoid any epoxy getting into the threading.
It should also work with the inserts still in the hinge, might just be a bit more difficult.

Here is a picture of what I'm working with. The picture of the hole is near the bottom of the album.

I was thinking of using bondo or something like this.

Of the two, which is better?

The brace on my 37 tall broke during a move, so I used jb weld and a thin strip of plexiglass to reconnect and brace the brace. Sort of a braceception type situation.

Use expoxy putty like J-B Weld Plasticweld epoxy putty https://www.amazon.com/J-B-Weld-8237-PlasticWeld-Plastic/dp/B003S2E4UE/ref=mp_s_a_1_2?keywords=Plastiweld&qid=1574710414&sr=8-2. I used it before to fix a cracked garbage bin. It dries tough and quite sturdy. Although keep in mind, when it is dried/hardened, the color is white.

What kind of case and what kind of switch? Do you have a picture? Are you sure you need a plastic filler and can't use something like a rubber moulding?

There are a number of epoxies and putties like auto body repair kits that you can buy that could do what you want, but most require careful application, then sanding and painting so you can get it flush.

I think this one could be a general purpose one to look at and work with.

Could you use something like this: https://www.amazon.co.uk/JB-Plastic-Weld-Fast-setting-Reinforced/dp/B003S2E4UE ?

Then potentially sand down, there will be a blemish - but it won't but a big crack instead

Taking the disc in/out of the clips is going to put pressure on that spot. The disc spinning on the spindle inside the cube can put pressure on that spot. It could easily spread.

I cannot see the other side obviously but it looks extremely close to the data section of the disc.

The crack can be "welded" using something like this epoxy. It will not be a pretty fix but it will prevent it from spreading. Doing this will reduce the value of the disc though so; a trade-off?

If it were me. I would contact the seller and tell them what you have found. Most reasonable sellers will work with you on either a discount or a refund. If the discount is large enough it may be worth just keeping as-is.

Are either one of these the right product?

The water reservoir is made out of plastic (I believe), but the first one is specially for wet use and the second one is more geared towards different types of plastics moreso than the first one.

Not sure what to pick. What do you suggest?
