Dado Rail removed. . .Next Steps for a beautiful Finish

Hello everyone,

I need some advise on on two issues. I have started a project of redecorating my hall from it's previous owners.

Firstly, I removed a dado rail from the wall. The wall is concrete and the nails were steel so slight damage to where the nails were in the wall was inevitable. I know that I will have to fill holes where the nails were with polyfiller and sand it down to a fine finish so that it blends with the plaster. There is raised edges of paint where the paint used to meet the dado rail, clean plaster where the dado rail was and then raised edges again. I'm not so sure about having to polyfill the entire area where the dado rail was. I feel that the raised edge doesnt warrent to be filled, but yet, if painted over it could be very noticable at the finish. . . I have thought about using a good sander to blend it in, what do you think? also, larger areas of paint has chipped off and was wondering who it be best to leave them areas and paint 2-3 layers of undercoat to try and bridge the paint gap as opposed to trying to pollyfill. . . . All comments and feedback very much appreciated. I dont want to make the move and prefer to approach it with caution so the end result is perfect. . .

Secondly, is there any checmical out there that disolves paint from PVC. . At my front door entrance, the previous owners were so distasteful and have managed to get purple paint all over the PVC around the edges of the front door. . . I am in search of a chemical that will remove the paint and prevent me from scrathcing the PVC with a scraper, metal scrub etc. . .

Thanks very much for your feedback - much appreciated.

Thanks,
Radioad.
