This product is very thick and needs a fair amount of thinning to be sprayed the recommended thinner is tot. boat 100 but is or was $16.00 a qt. if you are some where xylene is available that is the way to go remember you will need to spray 3 to 4 coats min. and equipt. clean-up after each coat. Home Depot carries the Klean Strip line of products they may still carry xylene or a product called painter's solvent which is a replacement for xylene, mek, tolulene and naphtha around $18.00 a gal. but of course not in CA. because it smells . The goal with a thinner is to flash off fast enough not to run but not so fast that the paint can level to avoid excess sanding. Read the tech info on the web site, it's all there. Product is excellent when used as designed, worked very well for me. I'm always happy to hear of people who are doing things for their selves if the end result makes you happy then the job is perfect! **Q: Can you use the topside paint directly on this primer, or do you have to use the topside primer?** A: Topside paint will work on total protect no problem. **Q: Can I use this to refinish a porcelain sink?** A: I would not use this on a sink.
