I’m looking to dye m Blue 70 XR7 door panels with SEM Landau black. I’ve done this before and it turned out great.

Bulldog adhesion promoter was recommended by a friend to spray onto the vinyl first. Any experience out there with this product on vinyl?

Thanks

I’ve never used the Bulldog before, but have used the SEM brand adhesion promoter with great success.

I’ve used the SEM vinyl prep stuff and it worked good.
