...I just bought a gallon kit of SPI black epoxy for $207 delivered! For the best quality epoxy primer there is. I use it for leveling like slick sand, for sealer before base, for the best possible foundation on bare metal or fiberglass before paint, also can be used for ground and finish coats on frame and unexposed bits. And IMHO it's the by far the best working, sanding and most durable epoxy I've ever used. And for $207/gal! If the salesman made a mistake and it's more money, please don't read this until after it's shipped out.

I did a true torture test with it in a not recommended application a few years ago. Tried it on top of teo bumper plastic partially embedding the base of fiberglass mat into the wet epoxy as a possibility to firmly custom reshape a plastic bumper with fiberglass. I gave some samples only a couple of weeks of drying time & it fought hard pulling on the fiberglass strands, but did fail with enough pulling. Found some other samples over a year later & the dry fiberglass strands all snapped where it met the epoxy after enough pulling without affecting the epoxy bond to the plastic. So after being given true full cure time, that's truely bad ass tough.

Wow, that's impressive. After you use it a few times and get the learning curve down it's evident that other epoxy's just don't compare. I'm using up a quart of another brand black and the build is nowhere near the same, the texture when sanding isn't and I found myself after putting on many coats, unhappy with what was there and looking for a filler. I just nutted up and ordered a gallon of what I knew would make me happy. Hate to sound like a paid spokes person (Im certainly not!) But this coating is truly impressive.

Slofut check your tech sheet on the " other brand of epoxy " to make sure body filler can be used over it. Just talked to a fellow who has a redo because of this .

This is very important what said here.
This is exactly why one filler company, when asked about filler over epoxy, says, check with the epoxy company.

Of course, the problem is does the company rep even has a clue, and worse, if its private-label crap, they can't even get their clear solids right
let alone give you a straight answer on something like epoxy.

I'll be damn, I got a complimentary gal of waterborne w&g remover with my order! You guys are the best, thanks Barry and SPI! Love the new tech manual and price guide, nicely redone. That Isotta Fraschini is to die for and is a huge statement for SPI.
