Hey crash, if I remember right you use strictly SPI Epoxy for blocking. If thats correct, what do you use for blocking and how do you clean the epoxy between coats?
 
I use 150 on the first round, then 150 followed by 220 for the second round of primer after bodywork, then 220 followed by 320 for the third round. Then I usually use a couple coats of 2K, so I don't really use an all epoxy process, not usually. But you can if you want to.

Wipe with #700 before spraying.
 
Thanks Crash, that was what I needed to know. I'm just practicing on the bottom of my cab floor but its going to get bedliner. Really just trying to get a good feel and thought this would be a good way to do that. When they say two wet coats...........does that mean a single pass over the entire surface spraying a wet coat, then let flash for 30" and come over it again with a single (one pass) wet coat? I have always had a tendency to apply too much paint by double coating (two passes overlapping 80-90 percent, then doing that again after it flashes. So I think I should be getting used to a single wet coat without so much overlap. Two wet coats means two wet coats, not four.
 
Percentage of overlap is tied to fluid flow (nozzle size and needle adjustment) and speed of travel. All three will affect the amount of material laid down. Lots of overlap is generally a good thing because it tends to create a more uniform finish. think of it as lots of light coats, where less overlap is fewer heavier coats. All the mini-coats put on by your pass technique adds up to one coat applied. You will know if your technique is wrong with the epoxy, especially on the first coat. If you tend to spray too heavily, try turning the fluid adjustment in a half-turn before trying to fix your technique. But sometimes you have to adjust your travel speed as well. It's all a balance.

And yes, two wet coats is what you think it is.
 
Thanks Crash, that gives me more of a goal to try and get some better technique down. I sure did like my first experience with the SPI Epoxy. I used a litter filler over it in a few places and it all sanded out really nice.
