Southern Polyurethanes Inc. SPI

After reading excellent reviews for SPI products and speaking with Barry K on the phone, I decided to use SPI epoxy, Turbo 2K, and Universal Clear on my 1934 Chevy restoration. I have used their epoxy a good bit and I like it a lot. It is very durable, it covers well, and does not burn back a lot when welding.

Now it is time to get my rod painted. Since it is the dead of winter and I do not have the facilities, or the experience, I decided to have a professional do the job. The guy I chose normally uses PPG, but agreed to try the SPI. After using the epoxy he liked it. However, he is worried about the Turbo 2k. He says it seems thinner than the PPG high build, it does not build as much, and it is going on so dry that it is almost immediately dry to the touch. My guess is that he is using a 1.4 tip even though the tech. sheet recommends a 1.5 - 2.0. Has anyone else attempted to spray turbo 2k though a 1.4 tip? Is this the problem? He is using the SLOW reducer.

Due to his bad experience with the Turbo, he is questioning using the Universal Clear. Any suggestions?

As I told the gentleman doing the work for me, I am not using SPI products to cut costs. I want to use the best materials available on my car.

Never used SPI Turbo 2K, but their Universal Clear is basically PPG DCU2002. Tell your paint guy that he will love the Universal Clear, or have him give Barry a call.

the turbo will be a bit thinner than the PPG high build..if he wants a high build product then go with the SPI high build..High build is 8000-1 and turbo is 6300-1
the turbo is very fast drying for those who like that kind of product..You will love the universal clear as I have found it to be the one clear that i can shoot gun done..

Personally I like the high build for filling small scratches as I use it for that..

Also make sure that he has a tech manual from SPI and is using the reccomended tip sizes as I have found that some of them have not read the manual and have issues
because of that..

Shine,

If you can get the Turbo to flow though a 1.3 tip, then what do you think would cause the Turbo to go on so dry? How much do you reduce it? My painter says that his gun sprays PPG high build with no problem and that it is thicker than the SPI Turbo, so he doesn't understand why he would need a bigger tip.

Just a little background....I'm using the Turbo 2k as per SPI recommendations because I am painting the car black. I would have chosen the regular SPI high build, but it does not come in black, and I was trying to keep everything black the whole way through.

too much pressure , gun adjustment , maybe a small chunk of primer in the nozzle . hard to say. if i shoot it with my iwata it really gets wet. i have an old sfg sharps for primer. have a 1.3 and a 1.4 . primer is all they are good for. it's probably best to shoot through a 1.4 but either seem to work.

Their clear is top notch ....He'll love it.... I do question his ability as a "good painter" if he cant figure out this simple problem on his own though...too much air and not enough fluid....any primer will do that...sounds like a syphon gun probem.but if its a gravity gun its even easier to fix...

Thanks for the advice everyone. I talked to Barry from SPI on the phone about this too. He said basically the same thing, the gun isnt set up right or else it isn't being reduced according to the spec. sheet. I just have a hard time believing that my painter hasn't tried these things. From what I have seen and heard from others, he is the best in my area. I just think he is reluctant to use a brand of paint that he knows very little about.


The gun being used is from Harbor Freight...HVLP 1.4 tip.

I have yet to hear from anyone that has used an SPI product and did not think it was the best they have ever used.

IS THERE ANYONE OUT THERE THAT DISAGREES WITH THIS???

The epoxy is the best I've ever used at any price ,as for the other produts Their clear stands out there with the best...its the price the makes it the best bang for your buck.... but for the price their other primers are very good...You cant go wrong with SPI ...It's their hot line puts them over the top as a company ...I've never seen anything like it...

I've used one of their guns once. A buddy of mine bought a skid of paint guns at an auction a couple years ago. He as selling them to his friends for 10.00 each, he must consider me better than a friend, I got mine for nothing when I helped him load a car for a customer. I used it for some surfacer and it made a big cloud in my shop. I gave it to another friend who promptly put it to use in his trash can.
