Plastic blast?

["T. S. White" <tswrace@pacbell.net>]

Thanks to the sage advice of this list I have srapped the idea to sand
blast the firewall and wheel aprons on my TR3.

My new idea is to blast them with plastic beads.  This is non or less
corrosive I think.

Can anyone contribute salient comments on the advicability of this?

        Thanks,
        Tom
