Hey Mike,
I sprayed the 750 for my last car on Friday and I liked it with the w400. I can see that it would be a better clear for completes so I’m going to order up some 700 this week.

I have been using Deltrons DC4010(I think is the lower VOC version of the DC3000/4000) for the last 5 years or so and I can get it to look amazing! But It is such a sensitive clear when it comes to popping and die back even at air dry temps and it buffs like concrete if it sits for more then a day so I have decided to make a switch.

I’m in Southern California and they are very strict as far as VOC are concerned and as I recall they outlawed DX84 about two years ago. So I will stick with backing it at a lower temp.

Yeah, I noticed on the video you switched from the PPS for your clear. I have never used the RPS before or heard much about it. I thought they were all basically similar and had nothing to do with how clear would lay out. I’m interested to hear the difference. The shop that I’m at is a smaller shop that really keeps a tight end on the paint material bill so I would get questioned if I purchased the RPS when I have been using the PPS for about 6 years now.

Thanks for your info Mike!

Hey Ryan, what’s happening! I think the EC 750 is OK, I’m not jumping for joy or noth’in. Its NOT 894 that’s for sure. I cried when I used the last of my 894. Out with the old and in with the new hey Ryan.

Anyways, I use the 750 for completes ONLY. Everything else I spray is with the 700. With your popping issue, don’t bake it that hot. Only go 150F and you will be good. You can use a cap full of DX84 ENHANCER and that will help the clear harden up better. Also what you can do before you clear is bake the base for 5-10 minutes before you clear. That way you will be rid of the popping. If you use sealer and are using slow reducer, switch to a medium reducer and that will help the popping issue as well.

With your Iwata gun for clear, crack the fluid needle out four threads on the dial and spray at 35Lbs. I find the RPS cups work much better for the clear than the PPS cups. I switched to the RPS cups for my clear and found the appearance looks much better than PPS did.

One more quick thing Ryan, spray the 700 clear on and let it set up for three minutes then hit it again, I find a little flash time between coats is good for flow and overall look.

Please keep me informed as to how it is working for you. Thanks for the kind words on the video, I might shoot another soon.

Thanks,

~Mike.

Hey Mike,
What do you think about the EC750? My PPG rep gave me both the 700 and 750. I used all the 700 with every gun I have except my w400LV and I was having some hard times dialing it in. I have just started to dip into my 750 with the LPH 400 1.3. So far I’m liking it. Just does not dry at low bake temp so i turned it up to 170F for about 30 min and i got some minor pop. So I’m still working on the right bake setting. Also just read some of your previous post about the w400LV. I have one more car to spray today and I think I’m going to break the w400 and give it another chance.
Awesome video by the way!

Thanks Will, glad to hear you love the clear coat. It took me awhile to dial it in but once you get it the EC-700 looks awesome. At first my rep stated a 1.2 mm tip was perfect for the clear but we did a little more testing and the 1.3 Iwata W-400 LV was the perfect gun and tip size for the EC-700.

I know after spraying it for a few weeks you will get to love it and your paint work will become spectacular. You can see me spraying it at collisionhub by clicking this link http://www.collisionhub.com/video/application-processes-using

Thanks Will and feel free to ask me any questions you wish or if you have problems please let me know and we can trouble shoot here.

Thanks,

~Mike.

Thank you! Today is my first time spray with the EC700 with 7080 hardener, it was great! The clear is awesome! It seems like it is easier to spray than the Sherwin Williams clear I used before. I was spraying a front end. I started with 1 medium coat, waited 1 minute, spray another medium coat, and then quickly spray a light coat. It looks not bad, not the best, but not bad at all. I will try your method with 1 medium and 1 wet coat tomorrow and see if it will look better =) By the ways, I love your blog, I will come more often, cheers!

Hey Will, I use a W-400 LV with a 1.3 mm tip. This gun I found is way better than the Sata Jet 3000 1.2 I was spraying with to start with. I bought another gun W-400 LV to try it with the EC-700/750 and found it works awesome.

I put the first coat down medium, not pebbly and not glassy, just a medium. I wait for 2 minutes and then spray the next coat on wet and glassy.

I have pretty much got it dialed in now.

Thanks for the question Will, hope to see you back on the Blog here soon.

~Mike.

Hi, i am kind of new to EC700. Just wondering. Do you guys use a W400 for your clear coat? I asked my paint rep a few days ago…and he said he doesn’t know of anyone who uses W400. He could not provide me with any info. What size of tip and cap should I use if i am spraying EC700 with a W400? Thanks in advance.

Hey Seamus, I have a question about your gun setup with the lph.400. I am using the same 1.3 and having a hard time laying this ec700 down on side panels. What do you have your material control knob set to? and on your first pass how much clear are you laying down? This clear seems like if I get it dialed in I should be able to save some time and the shop some money.
Thanks

Ryan

Yeah that’s awesome Seamus, when you turn up the pressure the fan will become larger so maybe turn the fan width down and you can then turn up the pressure a bit more to get better flow. Also I have tried using 5% reducer with the EC700 and it looks even better then with just adding hardener. I use Global 871 reducer and between coats I let it flash 30 seconds before I go back to back.

Glad to hear you are having better success,

~Mike.

Hey mike,
tried turning up my pressure and my sides are looking better. I sprayed standox for some years and it was thick, but not as thick as ec700. My fear with the lph400 was splitting my pattern with pressure higher than 18 psi. So far at 25 psi my pattern is fine wide open and has no dry spot in the middle. My use per panel is also good( have to keep material bills looking good) so i haven’t lost transfer efficiency. With my adjustments due to your advice my jobs are looking better with each application.
Ec 700 is thick!
