First post here after learning a lot from many regular posters :worthy: I am getting ready to paint a small (2.2 gallon) motorcycle gas tank, small fender, battery box, and oil tank with Spraymax and House of Kolor Aerosol Cans from http://coastairbrush.com/ and http://www.66autocolor.com/

Can someone suggest the best 2k primer for these parts (which are new, good condition,and bare metal) between the SprayMax 2K Epoxy, Spraymax 2K High Build, or House of Kolor KD3000 2K Aerosol (http://www.66autocolor.com/Aerosol-Auto-Primer-Spray-Can-s/50.htm?searching=Y&sort=13&cat=50&show=10&page=2)

As I understand it the HOK KD3000 has the adhesion and anti-corrosion properties of Epoxy and is very sandable. So, this would be the best for my budget rather than having to use an Epoxy and a Filler.

If it is not already clear, I am fairly new to all this so be gentle and all help is appreciated. :goodjob:

If bare metal then the standard 2K primer is off the list.

Unless you need high-build to block sand the parts, just shoot the epoxy primer then go to your base color. If you need the primer to give you enough film thickness (build) to sand it back down flat, then you'll need a 2K primer to go over that aerosol epoxy, because that epoxy is going to be thin. Also you will be surprised at how little coverage you get out of an aerosol can, hopefully enough to get those parts coated.

Got it. Any experience with the HOK KD3000? It sounds perfect, if it covers all the bases as well as it claims to-hybrid of epoxy (for adhesion and corrosion) and acrylic polymers (for sanding).

Not personally familiar with it, sorry. Looks good on paper though ;-)
