Wow, a lot of questions, I'm no expert but
I have a lot of opinions (LOL)
I do a lot of "small" collision work as a "hobby"
Usually only a panel or two, no overalls.
I have done a car a week for the past 10 weeks,
costs are a concerne. So the Euro looks really good.
I get 2 gallons of sprayable clear from a 1 gallon kit when
I reduce it 4:1:3, which works good for me. So it's very cost effective.
I still like the Universal too and highly recommend it.
I also like that the Universal has a "very slow" activator.
I try to stay with just one clear so I can keep my inventory low
and fresh.
The G2 is a polyester primer by Evercoat. Poly primers are basically
a sprayable body filler that give a very high build and they have less shrinkage
problems than a 2K. Really neat stuff, you need a big tip to spray them.
I use 2 different non brand basecoats, "Metalux" & "Genstar"
My supplier carries both and I pick by which one has the best color matching chip.
I get great matches with them.
They're both less than half the cost of a name brand like DuPont,
which I used to use but has gotten to expensive for me.
The spot putties can set up really fast in hot weather, you can adjust it by the
amount of hardener you use. I usually get less than 3 minutes before it sets.
I keep mine inside the house where it stays cool, that gives me more mixing time.
Once on the warm panel it goes pretty quick.
Thanks!
