  2. If Hammerite primer is like the paint, you'll never be able to paint over it without it reacting.
  3. ^Whs^ unless you're after a crackle glaze look...

  6. @crossy2112 Epoxy mastic is that Yorkshire for poxy mastic?:p
  7. Second that. It's non-porous so you can leave it as is without needing to cover it with top coat.

  10. You can use epoxy but you must re prime it before painting your top coat I believe.
    Etch primer is also good for rust proofing

  12. How about Galvafroid for the underside, or will you never get a top coat to stick to it.
  13. Bonda.

  16. As Matty said, Bonda primer, brush on straight from the tin, quick drying, normally a couple of coats is enough.

  17. What is "Rustbullet" good for?
    Have some but suspect it's a bit of a bugger to paint over without lots of prep .....
  18. I etched the underside of my bug years ago and never got round to using a proper paint it's been good till now. I brought the stuff when paint was paint so it was full of nastiness.
    I did do about 30 coats thou
  19. Bonda primer all the way

  20. Agreed, but I think they’ve gone out of business or been taken over. You can’t find their products anymore so I’ve been stock-piling. I’d be very happy to be proven wrong...
