I need to reinforce the back of fairing in places that have cracked and need to glue peices of ABS
Any suggestions as to a Glue that will adhere to this material. I believe MEK (methyl ethyl Keytone)
but I cannot source same.

I haven't used this myself, but have read many threads over the years where owners have used this to fix fairings with good success. Watch the how to videos which give a detailed explanation of how it works.
Permatex Plastic Welder. This seems to work great. Repaired a piece of fairing a couple of years ago with this stuff and its still holding solid. Once set it can be drilled, sanded or painted.

Cheers I will give it a shot

Acetone is the solvent for the styrene in ABS, as long as you remove the paint from the area you’re going to patch it’ll chemically weld the patch on
Sheet ABS is cheap and available from eBay
I’ve been using ABS pipe cement with considerable success, the stuff you get from builders merchants or eBay again
Like this
I use Plastifix.
I have personally used it and I think its brilliant.
Use in a well ventilated space though .
As mentioned, acetone will melt ABS. What I've done is mixed scrap ABS with acetone to make a slurry/putty. Then V-notch the crack in back and apply the putty. Wiggle crack slightly to work it in. Let dry and it's good as new with continuous material across crack.

Negative... acetone will not melt ABS nor it will not harm stock paint... rattle can paint yes... I employ acetone to clean the inside of the RC45 painted fairing...
I recommend employing a plastic welder...

Acetone will dissolve single-part paints, but won't melt cured cross-linked paint. That's what saved your fairings.
Make sure you're using real 100% acetone (2-propanone), not nail-polish remover "acetone". It most certainly dissolves ABS:

I'll make video to show you how to do this process. Must've done it at least 200x to repair broken fairing tabs. A blend of MEK & acetone will actually dissolve better. Most of the ABS cements are blends of MEK & acetone, along with ABS resin filler.
Yes, heat will work better as you'll get better penetration. Then build up and fill gaps with slurry (reduces stress-risers from uneven surface).
In the US, glue for ABS pipe that you can buy at the home store is ABS dissolved in Methyl Ethyl Ketone and Acetone.

I buy it by the gallon... Make sure you speak from experience before you forewarn...
Thanks for replies, job done with ABS pipe cement.
I make abs paste with bits of abs dissolved in acetone (leave overnight until it’s like toothpaste) and it works a charm. Bond is as strong as the parent material.
Best to stitch broken pieces together with a soldering iron first. Also a good idea to use pieces from the parent part just in case you’ve got two different varieties of abs. I’ve never had a problem using scrap but it never hurts to be careful.
Acetone melts abs but it takes some time. Overnight is ideal. Dries with micro pinholes on the surface so ideally sand it to finish. Great fir building up weak parts.
One drawback: dries a bit more brittle than the parent material but still has some flex.
