Trial #1
To evaluate successful products on second supplied buffing compound.
The top four products from the previous trial were diluted to 5% in 250 ml beakers using DI water and heated to 130 F.
Twelve preweighed coupons were coated with the red buffing compound using a handheld swab after heating. Coupons were weighed a second time to determine the amount of buffing compound added. Three coupons were cleaned in each solution for five minutes minimal agitation in an immersion tank. Coupons were rinsed for 15 seconds in a tap water bath at 120 F and dried using a dry compressed air for 30 seconds. Once dry coupons were weighed a final time and product efficiencies were calculated.
All four products removed over 70% of the buffing compound with immersion cleaning. One product, Polyspray Jet 790 XS, removed over 95%. The following table lists the amount of buffing compound applied, the amount remaining and the efficiency for each coupon cleaned.
