They don’t run poorly because of that. They run poorly because they are outta round Chinese junk.

I fixed a Cylinder head on a CBR 600 with JB weld. The bike was left with just water in it after a season of racing.... I bought it and JB welded it and rode it several thousand miles before selling it. Yes I told the guy that bought it and I know he road it for a few years.

I JB welded a oil cooler on our Cat955 loader Probably 20+ years ago and it is still running!

I’m sure I’m forgetting several things that got a JB repair all over the farm.

I modified the grips of my Glock 19 and 22 with Permatex 84145 Black Plastic Welder. I am not talented or patient enough to make it look factory, but once dried it matches the Glock plastic perfectly. I rough up the surface with 40 grit sandpaper and clean with alcohol before applying it. Will post a pic when I get a chance. I have used Devcon DA290 before and I think they are the same thing or at least super close to each other. Both produce the same gnarly fumes when mixing and behave exactly the same for me.

Best stuff I've found for surface prep.

Glass bead cabinet is the beast I’ve found for surface prep

 

[czar800]

I believe I used starting fluid both times and Preheated the areas with a propane torch... right or wrong it worked.

180 sand paper for prep/ Acetone for cleaning/ JB Weld. Works good for me.

Ok.

Here is the 22. I got rid of the worthless finger bumps, flattened it out, and created a sort of gritty texture.

JB is good shtuff. Used it for more repairs than I can remember. In the world of firearms many guys use Devcon to bed bolt action rifles to stocks, hopefully they don't forget the release agent. Used some 2part dough like crap in a tube...steal stick? Repaired a transmission cooler line temporarily...it's been on for a few years now still holding.

Smeared that locktight 2 part s-word on knife handles before pinning the scales on. Good s-word. In my experience the fast set s-word is rarely as good as the slow setting crap.

Still raffing

Devcon, JB Weld, Loctite, it really doesn't matter

As long as you mix it 32:1

 

[Spladle160]

Devcon 10110. Smells good and you can mix it to a wide range of consistencies. Sands and files nice with real good tensile strength. I've seen jb get soft and gooey around gasoline even after a couple days cure. JB also doesn't have great hold or tensile strength but... it still works most of the time and i don't feel the need to use a scale to mix it. prep is key. surface finish. cleanliness and if the job calls for it reinforcement. nothing wrong with mixing in a little fiberglass sometimes.

Maybe it's just me, but I think it would be nice if jb came in the twin tube syringe with the mixing tip. Yeah you loose a little product but I like them.

This is the 2nd jug I ever ported. It was on my 066 for a while and ran the pisss outta it. Then when my race saw took a chit, I put this jug on my race 066.
It’s ugly but runs pretty good. The JB felt just as hard as it did after it first cured. Gas or ethanol does not soften JB at all.
