Chemical strip or sand blast?

[vasker]

I was wondering is sand blasting absolutely necessary? Or could the same results be archived by chemical striping paint and old powder? The reason why I ask is I do alot of computer cases and if I could dip and strip it would save me alot of time, as opposed to sand blasting. Thanks

No matter what you need to etch the surface so the powder has something to hold on too... I use B17 to strip and blast to get a profile..

After chemically stripping use a conversion coating like Iron phosphate (Surcoat 915).
