WHAT EVER YOU DO, DON'T GIVE YOUR FRAME TO THOSE GUYS DOING GARDEN GATES AND BAKKIE RIMS
Sandblasting could destroy a good frame and the coating quality might not be very good.
Look for people that do decorative sandblasting on glass and pay them handsomely to do the job. Make sure the frame is properly degreased and bone dry. It will contaminate both the frame as well as the sandblasters materials and equipment and the company will be reluctant to help others afterward.
You must also first strip powder coated parts with paint stripper before having it sand blasted. The type of grid that is heavy enough to remove powder coating is to abrasive for your frame and will create internal stresses on the frame possibly leading to future failures.
When it comes to powder coating chose a matt black finish from the architectural powders as these will not fade with prolonged exposure to the sun and elements. DO NOT CHANGE THE COLOR OF THE FRAME AS THIS REDUCES THE VALUE OF YOUR BIKE.
Choose a powder coater that can pretread your frame in a phosphate bath. This will remove any greasy finger marks and will also edge the frame for better adhesion as well as provide corrosion resistance.
Look for smaller specialized companies especially those that do in-house work, because they coat their own products and the quality is usually very high. Some of these might not even advertise themselves as powder coating companies.
Sandblasting - You have to budged around R400 to R500 for sandblasting if done correctly using nothing more than a 80grid material like Microblast.(commonly used by the glass decorative guys)
The lighter the grid the longer it will take to get the frame clean so that increases the sand blasting cost but this is a small price to pay to insure longer frame life.
Powder coating - This will cost around R600 to R800 for a complete frame. I recommend you mask everything yourself. Use old screws or buy a few cheap mild steel bolts to fit into the threads. Never let them stick out on the other side because the powder coating on the threads will make them impossible to remove. Use masking tape on the swing-arm axle mounting point threads and the swing-arm gasket surface and swing-arm bearing and steering bearing areas.(if the powder coaters uses a phosphate treatment then you can't mask with masking tape until the phosphating have been done)

Sandblasting can either be done by Schipper Steel in Paarden Island or A&A Powder coaters in Killarney Gardens.
Schipper steel is the best although they do not market themselves as powder coaters they will do the odd job. They are a sheet metal fabricator with their own in-house facility. They carry a limited range of colors but only the best Aczo Nobel powders for architectural use.(good UV resistance)
A&A powder coaters on the other hand might have a bigger range of colors available(although black should always be the color of choice for a good clean GS restoration project)and they are the only people in Cape Town that will put the frame into a phosphating process. (remember the masking type can only be added after the phosphate treatment has been done).
