I have 35ml of Opti-Coat in a syringe for sale. PayPal only. It should do a least 2 large cars with no trouble according to Optimum. I take no responsibility on the application. Go to the Optimum Forum on how to apply. $85.00 includes shipping. I paid $90. First one to PM me. ****This product leaves a hard acrylic finish that must be polished off if there are errors in the aplication. You take full responsibility on its use****
