I've had a good look around here and the web generally to try and find a sound method for build up treatment on panel rust repairs, under body, inside of new panels etc. It seems quite apparent that it comes down to individual preference and cost / time etc.
I wonder if you guys with experience and results could let me know whether the following would be suitable for the areas I've titled. I am not too bothered about finishing as I will be sending Ruby off to the paint shop once she is ready, but am very keen to ensure I provide a good level of protection in the paint prep and be sure that what I do would be acceptable for the paint shop when I hand her over.
I understand that the paint shop will prep her anyway, and I might drop in to have a word to make sure I don't apply anything that would cause them trouble, so here goes -
Treatment of localized rust and panel repairs.
1. Flap disc to expose bare metal and extent of rust to area.
2. Wire wheel to remove surface rust and in pitted areas.
3. Ball pin hammer out any raised areas and create minor indent to accept filler.
4. Apply rust converter.
5. Apply etch primer.
5. Apply seam sealer.
7. Apply 90% Zinc primer.
8. Apply filler and rub down.
9. Apply etch primer.
10. Apply stopper and fine sand.
11. Apply build up primer to cover protect until paint shop.

No I don't have shares in Bilt Hamber, but have read good reports, plus there are benefits in using the same manufacturer with compatibility and such. I guess its not the cheapest but my umble like experience has shown me time and again that there's a reason why stuff is cheap.
I would really appreciate some comments on whether you think this strategy for body prep is suitable, of if I'm way of the mark.
Thank you in advance.
