This stuff is great! Use it for everything from appliances to kitchen formica counter top to the bathroom. Will try it on the counter top in the Monty soon. It doesn't put a high shine on, but it seems to act like a "sealer" for easy clean up. I asked their consumer hot line if they tested it on fiberglass, they had not. I would love to try it on the Monty. It possisbly could be a good answer for an easy removal of those bugs.
You can't buy it in the stores anymore. Johnson people said the product lasted too long so they pulled it off the shelves. I buy mine direct. Kind of spendy. 6 spray cans about 42.00 including shipping. I will be ordering again soon. Those cans lasted me about 10 mo., plus I gave a can to our daughter. SC Johnson of Racine, Wis.
