SPI Bedliner over other brand?

[mehal]

Anyone ever spray SPI Bedliner over another liner? I have an early Bronco that had the floor and bed area lined over a decade ago. It must have been Rhino Lining or whatever was popular back then. I now have the body off the frame on a rotisserie and want to spray the underside along with the firewall and bed floor again so that everything matches.

Should I try and remove the old stuff or just hit it with a quick media blast to scuff it up and then put SPI over it?

Any experience or advice is welcome!

Thanks, Mike

Just clean it up like you said and shoot, been done 1000's of times.
