Restoration of Sandcast Frame 5369/ Engine E5479
UK Pete:
The upol etch primer is good and when i welded the hinges on that is what i used on that area, the rest of the frame was done with zinc 182 primer
The finish on hammerite is superb if you can get it on ok, as rich says the formula is shite now it seems to lack pigmentation and so needs many coats

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 CB250K had mega thin paint anyway Rich ;D, so it will be bog standard then ;D ! How do I tell if its old or new formula?
A new guy at work's best buddy owns a large refinishing outfit, perhaps they will bung my frames in their oven. seem to remember I fixed something for him once, and I wouldn't take payment.

You'll know Ash
If you spray it and the part goes black it's the old good stuff if you have to spray it
5 times and it still doesn't look black it's the new stuff ;D ;D
