I hate

The new Nitromors formula. Totally fucking useless. Literally. Hasn't even begun to remove the paint even after 2 coats. Last time I used it, it stripped Hammerite on top of factory paint in minutes. And it cost £9 for a piddly little tub.

Same with Evostik impact adhesive - gone water based rather than solvent based (presumably to protect the snoo gliffers from themselves) and now, rather than being one of the most awesome glue systems out there, is useful only for DIY post-it notes.

There is still some of the solvent based stuff out there. I have stocked up.
