SEM 38363 Sand Free - 11.6 oz

Great preparation product to apply prior to vinyl paint. It really helped with paint adhesion.

Can't go wrong with SEM

After calling SEM and getting some very helpful information from a nice gentleman, this was a simple job. I'm changing the color of the interior of my classic car, and I started with the console. After you spray the Sand Free, you have 30 seconds to lay down the first coat of paint. (The paint was also SEM for hard plastic). Apply 2-3 coats. I reassembled the console, and it looks great! Hopefully it will stand the test of time, as far as scratching or peeling...fingers crossed.

You have to apply adhesive before you spray the color coat. This is only for plastic that smears when rubbed with acetone. If it doesn't smear use sem regular spray adhesive. They are not interchangeable.

Quick delivery. Item came as described

did prep job very well paint is over a year old on my seat and still looks good. this bike is exposed to weather all the time.

This prep spray is essential if you are painting PVC door panels. I made the mistake of skipping this step on my first set, and the correct SEM paint flecks off every time I touch it. Using this prep spray on my second set, the bond is amazing. I works exactly as advertised.

It seems to me that SEM Color Coat doesn't stick to plastic as well as it used to. I don't know whether this is because of reformulation due to VOC compliance or what, but Sand Free seems to fix the problem. Perhaps this is the chemical they removed from the paint? That's just speculation on my part, but it does make the paint stick better.
