Sandblasting

[Black Betty]

I have in the plans a set of used fenders, bumper and grill for the old yj that I want to coat with raptor liner.  I understand prep is golden with applying any bed liner, but was wondering if taking these parts to the DIY sandblasting place here in town would be a good idea?  I think it would be easier to clean up all these parts this way, and then just use a self etching primer on the bare metal in prep for the bed liner.

Any thoughts?

My bad...

Sandblasting is definitely the way to go...

If you've sandblasted right down to grey metal (and haven't delayed at all so that corrosion sets in), do you even need primer? I think that a big part of bedliner's adhesion is mechanical instead of chemical - that's why they have you scuff your truck bed with scotchbrite pads before you herculine it. Sandblasting should give you enough texture on the surface to get good mechanical adhesion out of the bedliner.

Originally that's what I thought too, but I've been told that the scuffing is to get through the factory clear coat and that the bed liner will not stick to bare metal very well.  I will of course have to confirm this with u pol.
