Has anyone heard anything about the Sherwin Williams Macropoxy 646 epoxy primer? I am having my 67 media blasted and they are going to shoot it with the Macropoxy when they are finished. The guy says I can do all my body work right over top of this and when ready then have it painted. I just wanted to get some insight on this particular primer from you guys. Thanks

Rob,

I am using the DP800 Dimension Line that Sherwin Williams offers. I like it and it is strong and easy to use. It is a 3-part system. Hardener, activator, and primer.

Epoxy primer is a good thing to use; Yes, you can do body work over it (if it's light body work )... The same is true of similar products from PPG.. (which I also prefer in order to stay within a family)...

Thanks Guys, I am just curious because I never heard of the Macropoxy until recently and the company highly recommends this primer. I will stay with sherwin williams for the top coat, supposedly this Macro is a top coat also from what I heard, or at least the subframe and underbody can be left as is when he's finished. If anyone has any more comments let me know.Thanks

I have been restoring cars for over 30 years and have used many of the Sherwin Williams products and have had great success with them. The new 646 is an amazing product. BUT do not us any heavy fillers over it. try to stay with the new light weight microspheres fillers and dont build up over !/4 of and inch filler.Then when priming use the new product called Slick Sand by Evercoat. Its a new version of the once famous Feather Fill. This product is unbelievable and is a superior product for filling scratches and for blocking purposes. It really doesnt need to be top coated with primer , but i do for fo a final sand befor sealing and painting and have had flawless results.

Greg thanks for the response I was getting worried there for awhile about this 646. I have some minor body work to do(I Think, I hope) I will keep in mind not to go more then a 1/4 thick, I am pretty sure theres nothing major that will need that much. So after my body work and block sanding I should just spray those areas with the slick sand and maybe some primer then I will be ready for my top coat.

Thanks Greg
