Congrats on the new vert! Hope you got a BLACK top (as I wish I had). I am on my 2nd vette conv. (both w/ tan tops) and I ditto all the previous comments about Ragg Top. Couple of addtn'l hints: NEVER leave the top down for extended periods. Not even overnite. The longer the top stays in the down position, the more difficult it is to get the creases out afterwards. Secondly, dust and dirt are your enemy. If you keep the car garaged, cover the top with a car cover or an old sheet. I use a cover (for top only) and a Califorinia duster for the car. Do not use the duster on the conv. top as it contains an oil. Remember if you allow dust or dirt to accumulate on the top and then put the top down, it will rub and grind into the fabric as you are driving.
After washing, make sure the top is completely dry before applying the Ragg Top preserative. The preservative is a sealer much like a "Scotchgard" product and will seal in the moisture if the top is not completely dry. Just my little .02 worth. Hope it helps...
