I have used on a winter beater the magnetic paint I think it was chassis saver paint .you put your fibreglass cloth over were you want it and paint over with the paint and let it soak in and it had worked very well even though I did not think it would I took a few grommets out and after it dried cut out the holes to put the grommets in and I had the little cutouts for a while to show how it had worked .
