Where do you get a good epoxy primer? Auto body supply store? Any ideas on dealing with flash rust for a part I want to just polish up a keep bare. Just dry it fast, & polish it or hit it with a wire wheel? What is a good filler? Some thing that will hold up good. I have heard of metal fillers.
You guessed it. Ya gotta get the good stuff from autobody supply stores...That includes good fillers.
DON'T spray epoxy without a quality respirator...Epoxy is plastic and coating your lungs in plastic or any paint for that matter is very, very bad.
For fillers I preffer a light easy sand filler like featherlite...No particular brand applies here except
"NOT BONDO BRAND" The good stuff mixes, spreads and sands so much better.
If there is a chance for the filler to get any moisture to the backside (like on a spot welded seam, use a fiberglass resin product like tigerhair or resin gel for the 1st coat.
Plastic fillers are not waterproof and moisture is what causes them to bubble the fiberglass resin IS waterproff and will help to keep moisture at bay.
If you have a steel part, like custom exhaust chambers etc.... that you want to keep in the raw steel finish instead of painting them, coat them with
Mop & Glo about once a month, no kidding. My brothers '74 Kawasaki 750 Triple has custom exhaust chambers on it and it's been raw steel for a couple years and still look like new....Smells great when it's running too
NOTE: If you plan on painting it, DON'T cover it with Mop & Glo or you'll never get paint to stick to it right. If you just want to keep it bare until you paint it just plan on sanding it if you don't want to cover it in epoxy right away. Unfortunatly I don't know of any cures for this.
