What kind(s) of glue work best for bbx repair? What kind(s) DON'T work?
Any tips?

Thanks!

depending on the repair...ive used car model glue...for stronger repair applications...a plastic weld glue...or gorilla glue strongest stuff,but don't use too much its expands when it dries...

i use plumbers or marine clear "GOOP" , and nothing has ever failed to hold-- but its a 24 hour set-up.
i think (??) the plastic weld glue is supposed to be much faster and even stronger

Looking for something that will hold thin plastic bonded on the edge.... must be strong and allow the entire piece to bend and flex...

OK, I am looking to fix a JVC PC series back cord cover that got all busted up in transit because the seller was a moron.

thats a hard one spud as you know that most glues work real good but depends on what part, i have use numurus glues some with good results and some not to good especialy when it envolves moving the piece in an ackward movement, like for instance a battery cover those 2 snap pieces they flex because of a thin plastic as you push down to snap in place if it breaks well you can glue it but you run the risk of it breaking beause of the glue being hard and that where the thin part of plastic does its job, it may just snap en that same place as soon as you put a bit of pressure so it really depends...

yeah plastic is tricky at times to repair..trial and error at times...

tho one member that was good at repairing plastic parts was TY..."frank" he usually made new parts using steel putty and sanding it down..

ok spud --if the parts need motion -- then the goop does have some flexibility

I use two glues.
Super glue and epoxy.
But dont use 5 minute epoxy its not very strong.
Use the super glue to hold the parts in the right place first.
Than add some epoxy along the edges and around the cracked part.
I used this to fix a cassette record tab leaver-sensor, for small parts.

Hmmmm. I am concerned about the cosmetics as well.. Perhaps the best compromise would be to glue the broken pieces with a backer on one side of the wire cover. Then it would look good when installed and be very strong, but yet retain good cosmetics on the outside.

Maybe I should post some pictures of the parts as well... I have one shot at this to make it look good and any advise is greatly appreciated.

I used this idea to fix a tuning knob and believe it or not its just as sturdy now as it was when new

Maybe a picture of what your gluing might help.

I'm a very ardent fan and user of Super Glue Gel and using Zip Kicker (cyanoacrylate accelerator on it). This provides a marvellous mix of the gap filling qualities of thicker glues and the accelerator forces the bond to cure instantly with a massively stronger bond than air drying. I've had the plastic break before the bond on many tests and trials with it.

Zip Kicker is also called FlashTac under another brand, should be sold anywhere model car/airplance/boat/etc kits are sold.

Good luck 71Spud!



Rock On.

For severely cracked BBX encasements (front or back) I glue all the busted out pieces back together with super glue, then reinforce it from the inside with fiberglass. It works incredibly well. I cut 1 inch squares of fiberglass matting (as many as needed). Then I brush a thin layer of fiberglass resin on the inside of the encasement around the freshly glued area. Next, I start taking one 1 inch square at a time and laying on the thin coat of resin and work each piece in with a small utility brush dipped in more resin. I work the fiberglass squares all around the affected area. Let that dry and do a second coat. It's an INCREDIBLY strong repair.

Super glue does not stick well to some plastics.
There sometimes a different types of plastic that super glue will not work well with.
Sometimes it works good and sometimes it dosent ?!?!?!

Parts on a cassette transport are usually made of nylon which super glue will not work as the bottle that super glue comes in is nylon.
Nylon will look like its been glued but its not strong and will fall apart easy.

I use 3M adhesive we have at the body shop set to firm in like 1 minute and unreversible within 6-8 hours... the pieces aroung it will break first, I'll have to get the part number Monday, but it is commercial and requires a applicator gun...

It's black in color though, I usually do "touch up" paint work on my boxes that need it anyways.

I think the price is 20-30 $$$ the only bad part is having to have a gun to mix it (2-part)...
