my limited experience is that it cost way more than you would think to paint a frame and it is lot of work to get it to look good I would go powder coat

also spray paint from hardware or auto stores can may a great looking result, but it will not be as durable as if you use auto paint. (depending on wear you live you can get auto paint put in spray cans)

good facemask with filters is first purchase (60 buck or so and my not be really enough for auto paint)
paint stripper
degreaser
rags, brushes, sand paper ,tack cloth gloves, miscellaneous
sprayer of not using spray cans (I used a pre-val sprayer one bike to spray auto paint)
acid etch primer, sandable primer, color coat, clear coat

easily 150 to 200 before auto paint

1. take bike all apart
2. strip paint, anything left will show
3. degrease
4. mask
5. acid etch primer
6. sandable primer
7. sand, may need to do another coat of sandable primer
8. color coats 2 to 3 with proper respray time between
9. clear coats 2 to 4 depending again proper respray times

that is what I recall anyway
