my exam is soon so i dont have much time to praise, but: it is a wonderful sight to see a lecturer who really knows to give a lecture, not only knowledge-wise, but also the whole story, speaking style, everything! respect!

Thank you! I'm supposed to give a lecture on this tonight, but have no voice. With only one, 3 hour lecture per week, missing a class is a big deal. I am including your presentations in a virtual lecture for my students. I really appreciate you putting these up!

This was very helpful!! Please keep making more videos. You're awesome!

Thanks it was really helpful I'll be grateful to you 😊. We aspect more beautiful videos like that one

Being a painting contractor, we run into a lot of homes, rentals with mold, pet and tobacco smoke odor problems. Painting the inside walls will not remove the odors as they are impregnated in the drywall, carpet, upholstery and drapes making the home harder to sell, or rent looks good smells badly. If you have to repaint, the inside walls add the Ionic Paint Additive, one treatment will remain effective for 8-12 years.

Thanks a lot for the nice presentation, that is very comprehensive.
