Plastic Adhesive
I have recently bought a damaged repairable MX5 just to keep me out of mischief. The wing mirror mechanism that allows it to be turned in manually has
been broken and even second hand ones for a Mk3 are expensive. Can anyone recommend a very good plastic adhesive that I can use. I recon to be able to
drill and use long self tappers but need the adhesive as a back up strategy at the same time.

Apparently JB Weld is very good. They do different glues for different applications. I've just bought some JB original because I've read
that it can be used to fill in pitting marks prior to powder coating.... Not had a go yet so we'll see whether it works or not...😊

tbh I usually just use a soldering iron to fix car plastics, just as simple as welding. Unless you can identify the type of plastic and the solvent
for it, this maybe a better solution. Saying that I broke the Fiesta's adjuster and since I was the only one going to drive it just glued the
mirror on in the right position with some tiger seal

If it's a clean break in the plastic then I've generally found Loctite superglue pretty strong. The break does need to be clean though as
the glue is not a gap filler, just a means of bonding parts. I've bonded bit of SWMBOs wing mirrors back together using it successfully (bits
of the kids plastic toys too).

Ask your local motorcycle workshop to see if they have any as INOTEC produce a 2 parts adhesive that an be drilled and tapped, probably not worth
buying the kit as it’s very expensive but worth getting them to do it ? Think it’s INOTEC Topfix

Model shops often sell small bottles of a solvent adhesive for plastics - look for shops that sell posh/expensive plastic model kits. Use a brush to
paint the stuff along the crack and, when the plastic softens, hold the edges together until the plastic hardens again. Doesn't work with every
type of material, but it's very effective when it can.
It's effectively plastic welding.

I think David’s referring to Tensol liquid cement which is fed into joints via capillary action. We have had a fair bit of success with the hard
plastic glue bought from either Toolstation or Screwfix

If there is room, build up behind the crack with fibre glass, had worked for me.

Devon Plastic welder, like a 2 part epoxy but will even stick "ungluable" plastics. Rebuilt a smashed door mirror cover on a Kadett GSi
back in the day and was tough as hell and lasted donkeys years
