I would give it a try anyway though.... Just make sure that after you spray it down... wipe all the excess off and maybe let it sit overnight. If it proves to be a problem scrap it... I don't mean after one ride you will have alot of dust on it. I just know the conditions there and u will get dustier than say myself over here. But.... u would anyway.
I remember not long after I first got over there... I didn't know enough to get out of the way of the kings motorcade....

the police took care of that right away.

drove me to the edge of the road.
