## Questions & Answers

**Q: Getting ready to paint a plastic canoe. Will this product work well for that?**
A: Without knowing the type of plastic the canoe is made of I can’t say for sure. 
It’s designed to be sprayed on, then the paint applied between 5 and 15 minutes. 
When used on my door panels, I can only guess that it has helped with the adhesion since there have been no spots where the paint has chipped off. 
SEM is a great product line. 
I would recommend using this product to prep the canoe before painting, especially since it will be in water

**Q: Should the sem 39863 aerosol can have a rattle ball in it?
have shaken it multiple times and it does not seem to have one??**
A: Mine also does not have a rattle ball.  I got it a couple of years ago. Worked great. I'm guessing its doesn't separate as much in the can; so it does need it.

**Q: will this product cover or repair cracked leather, arms rests in vehicles ? Thnaks**
A: No , I don't think it would .

**Q: I have chrome plastic grill trim which I want to paint black. Will this work if I scuff the plastic, use adhesion promoter, primer a black paint**
A: I have tried every adhesion promoter out there. I have sanded the Chrome completely dull. First a small rock chip then the wicking under the finish and now you have a chrome grille all jacked up with scratches and patches of black. Take my word for it just buy a black grille.  I have been in the industry since 1980. Nothing sticks to chrome. Period.
