no its not if you want to do it properly you will need to apply about 4-6 coats rubbing down each one with fine wet and dry paper obtainable in car shops, sheets are mostly dark grey in colour .
Rubb down using water and allow each coat to dry thoroughly before applying the next coat. If it looks ok don't rub down the last coat and just do each one lightly.
OR
Wait for a reply from the company or email again even telephone its quicker.
you will also need some spray laquer to protect the paint when completed.
