UK Pete:
Thanks guys
I have tried several paints , and made a decision that the nearest i could find to the old honda finish is hammerite, yes i did say hammerite, it is a f---cking useless paint when it comes to coverage you have to build up so many layers, the trick is buy a tin of black smooth thin it with 2k thinners and spray it firstly with thin misting coats then a couple thick
It takes forever to dry but i won't be using the frame for a good while so i will hang it up in a warm place and let it set, if after all that it turns out no good then i can always blast it off and start again, but saying all that it is drying quite well

Nice one Pete as I found a full 2.5l tin of that stuff in one of the skips after the floods we had in 2013.. bl**dy tin wasn't even rusty so God knows why they chucked it away.. well my gain. What primer did you use? I have a few tins of Upol etch primer but I don't know about compatibility with Hammerite smooth. Suppose I could try a bracket out first.
Cheers
RGP750:
You may be lucky with an old tin Ash hopefully it was made before they cocked up
the formulation,it is pretty s**t now unless as Pete says 50 thin coats and a day at 90 degrees to dry.
Good luck

The big selling point about the old formula hammerite and smoothrite was the fact you did not need primer or undercoat, just wire brush loose rust off, and apply, used it more than 20 years ago on an old garden bench with wrought iron ends, still holding up well, can't vouch for the new formula (E.U. approved ) which I understand is sh#t
