I just did some googling on the subject and it is an auto finish product that seems to be a sort of drop fill for clear coats. Auto clear coat is a urethane finish.

For repairing nitrocellulose you should only use nitrocellulose.

Some of the automotive scratch and chip repair kits are still nitrocellulose but it's an expensive way to buy your paint and the cap brushes aren't the best. That said it might be a reasonable way to go for a one-time drop fill. Search for Touchup clearcoat pen and then check the manufacturer's MSDS to see if it's nitro or urethane.

Sorry for my slow response. I thought I had my settings configured to notify me of responses. Here is the link to MSDS: http://www.autocaredp.com/static/pdf/MS ... nglish.pdf I don't know if I have the requisite knowledge to tell what it is. Thx, Mark

I can't really tell what the product is but it is very volatile. There is no urethane in it. But it is also definitely not nitro lacquer.
