Now Iīve never painted a frame my self, but since I have just read about respraying a frame this is the basic things:

1, Get hold of the nastiest paint stripper you can find. Coat thoroughly whole frame with it. Wear rubber gloves. Leave paint stripper on for slightly longer than recommended. Then rinse off while brushing lightly with a wire brush. Re-apply as many times required to remove traces of old paint. Clean with plenty of water.

2, Let frame dry. Do not use degreasers, they affect the paint when you apply it later.

3, When spraying move the can in smooth, even strokes.Apply many thin coats instead of a thick one. Gives a better finish.

4, When finished painting itīs time to prevent corrosion. Waxoyl is a classic corroision preventer to use. This is very flamable, take care. Spray inside the frame.

5, Grease and fit parts.

Paint and frame preparation:

Waxoyl: rust prevention (inside tubes).
Halfords Paint remover.
Halford spray paint.
Rubber gloves.

Hope this can help you in any way.
