I have used SEM brand products for years on classic cars, so when it came time to reduce my vinyl boat seats I knew SEM was a proven brand. I purchased this and used it to prep the seats after scrubbing with SEM vinyl prep scrub. Once the seats were completely dry I used this to clean them. Wow, what a difference. After using this and allowing the cushions to dry I applied the SEM marine Carver White aerosol dye to the surfaces. The dye etched in and is holding up great!

Used this after final prep before respraying vinyl upholstery in a classic convertible, that had been ravaged by mice in storage. Product prepped and softened the vinyl to promote excellent adhesion. Very pleased and the seats and panels came out like new.

Used on old golf cart seats that were beyond cleaning. Made them look better than new.

I had really bad cushions and it was costing me fortune to reupholster them so I googled and found this product and I promise you it is like magic. It worked very well on all my cushions and I have been using them for some time now and you don’t even notice they’re painted! I highly recommend a product. It is very easy to use and the final product is amazing. Check out the before and after of my big front cushion.

I totally recommend this vinyl paint I used it on my boat because it so faded and with elbow work it came out beautifully. Dries fast and excellent coverage on the vinyl seats
