Re: what every new painter must read

Hey total noob here!

So I've sinned and broken 4 out of the first 5 things told not to do. I had no idea the mistakes I was making when I did them.


*Never use a rust converter of any kind. NO MATTER WHAT IT IS. (Klean-Strip Rust Converter)
*Never clean metal or paint with lacquer thinner. **This one I haven't done!**
*Never use a metal prep UNLESS you are fully aware of how to neutralize properly. (I sprayed and wiped the rust treated area with "Prep-All")
*Never use an acid etch primer, unless you are doing used car work for a dealer or rental car work. (I sprayed "Metal Etch Primer" over the rust treated areas)
*Never even look at an aerosol can of primer. (This is where the Prep-All and Metal Etch Primer came from)

So in an effort to head in the right direction, I ordered a gallon of SPI Epoxy Primer/activator. But how do I best back up and start again. I've only done the rain gutter, floor and 1 qtr panel. It's a VW Bus so there is plenty of surface area left to do. But I want to do it right.

Thanks in advance for steering me in the right direction,

Welcome, dadembk!

Just sand off every coating you have put on back down to the metal with 80 grit, clean well with SPI #700 Waterborne Wax & Grease Remover, let dry well, and shoot the SPI epoxy after it has been mixed together and left to "induce" for an hour or more. Your surface temperatures must be above 65°. This info is straight out of the tech manual which you may receive with your order. if you don't receive one, you can download it here:

Reading the relevant sections is a great place to start.

Just curious as to which forum gave you the bad advice that lead you down the wrong path. Seems to me like 99% of the forums advise to do it just the way you said, they probably all watch TruckU and 2GuysGarage, LOL.

I'd say damn near all of them. On an almost daily basis I run across a thread where someone asking advice gets the usual POR 15, lacquer thinner, Rust Converter etc. replies. If you disagree, you're met with the old "I've been using this method for 89 years and never had a problem blah, blah, blah"


Thing is, I think people don't hang onto the cars long enough to see the problems surface, or they blame it on something else and move on.

That is the reason this is the only forum I ever go to now.. I used to participate on several forums, but it got to the point where arguing just isnt worth it!!
