Sandblast work?

[UpToNoGood]

I am making a headache rack for my truck and plan to have it sprayed with linex. My question is should I have it sandblasted and painted before I have it linex sprayed?

Thanks

I would call the place going to shoot the linex, and see what they have to say about it..

So I called them today and they wanted the headache rack unpainted and rust free. If it was painted they would have to scuff it up to have the Linex stick.

So blast it....

sandblasted, then sanded, then wash primed or equivalent, the wash primer provides the adhesion and rust prohibition, they don't care about it four years down the road, if you have pay a few dollars extra to have them scuff it, so what, but I cannot see linex needing a having trouble with adhesion on a wash primed surface, kinda like the discussion we had about powder coating(whether to or not) awhile back.

as long as it's bare with no rust there won't be no problem with the Linex adhering. i had my pickup bed shot 6 years ago and it is still like the day they shot it and i'm not easy on it. looking back at my first wife it might not have been a bad idea to get her shot with Linex. she got a whole lot uglier and worn out in the same time frame not to mention hell by comparison my Ford would have grown to be a Kenworth.
