If it's not very good it's not cheap. 
Stay with Loctite Various products in different strengths Great product.

By the way if you apply heat to loctite it will loosen up. Powerful air dryer will do the job if worried about paint. To avoid pain and suffering don't tell the wife!

On this occasion heat didn`t work, neither heat gun or blow torch made any difference, but these bearings will have lain untouched for 37 years so not sure what bearing lock would have been available then.

Does anyone have any pictures or a link to a schematic of the dash + headlight mountings on a MONZA. I think I have all the fittings but am wondering whether there are rubber bushes for the dash mounting bracket where they fit on the forks or are they just trapped between headstock and headlight bracket bushes.

Advice needed on repairing ABS nose cone that has cracks in it.

The Monza nose cone has been repaired several times previously but none are what could be described as either good or permanent (use of fibre glass). Has anyone successfully repaired ABS panels on the forum, all suggestions greatly appreciated

First of all are you certain it's ABS?

Go to your nearest model shop and buy a bottle of Plastic Weld.  You can also buy sheets of ABS to strengthen behind the breaks.

For a crack, try to ensure it's all as clean as possible, then with a drop of the liquid on the end of a flat blade screwdriver, run along the crack and the liquid will seep in. You will have to go over the crack again most likely to ensure enough of the liquid has gone into the crack. Do the same on the back. Then hold the crack together for a few minutes.
The crack will weld up and be almost invisible.

I have repaierd larger breaks in a similar way but adding bits of ABS sheet behind, again put plenty of the liquid between the parts to be welded and hold them together.

You will probably have to do your best to remove any fibreglass still sticking to the ABS and have a clean surface.

I always now have a bottle of this in the shed, and have repaired loads of plastic bits with it.

It won't touch polypropylene though.
Brian.

Better 5 minutes late in this world than years early in the next.

Thanks for that Brian, unfortunately our model shops have long gone but have ordered Plastic Weld online. The fibre glass literally fell off when I undid the mounting bracket and had not properly adhered to the fairing itself!!!
I am fairly certain the nose cone is made from ABS and that it`s original, so restoration was the only option as the pattern ones are fibre glass and look to be a tad flimsy

Update to ABS nose cone repair, Plastic weld worked a treat however we experimented with some plumbers solvent joint weld that also did the job and is available from Screwfix etc.
Another bit of the original bike saved so best result all round
