Tip Size For Reduced Epoxy Seal Coat

A little more priming and blocking and I'll be ready for the seal coat but I'm not sure what size tip is best for a 1:1:1 epoxy seal coat. I'm a novice so if there's a reason I should be thinning it to a different ratio I'd like to know. Also, I'll be using a Starting Line gun.

Go to the homepage and find the perfect paint job write up. Also, find the tech sheets and print off a copy of each of the products that you're using to refer to.

Dont try to out think the formula. 1 full part of solvent is already alot, most "other" epoxies dont want you to reduce it more than 10%
 
I assure you my choice of a 1:1:1 ratio didn't come from experience or knowledge. If there's a better ratio I should be using I'm open to suggestions.
 
1:1:1 is ok to use, I think quite a few have used it at that. I usually never went that far myself though, but I'm far from a pro.

1:1:1 is a 50 percent reduction, so you have your epoxy mixed and reduce that by 50 percent.

For example you have a 20oz mixed cup of epoxy and to get to 1:1:1 you need 10oz of reducer. 10oz of epoxy, activator, and reducer making up equal parts of 1.

I always reduced mine in the 15-25 percent range and I liked it there. It gives a little more insurance on sand throughs should you have any.

So for that same 20oz cup I'm adding 5oz of reducer to get 25 percent.

When it comes to mixing in 3 parts it's easier to mix by ounces in my opinion. Hopefully this all makes sense.
 
1:1:1 works really well going over something that is all one color, sanded with 400-600, for adhesion purposes. If you have a lot of sand throughs to metal or underlying layers, 1:1:.5, or 25%, is better. Just remember the more you reduce it, the more transparent it becomes, and the less it will fill imperfections.

+1.
I have also mixed 1:1:.75 or 37.5% for a bit more hiding of primer spots. The less reducer used in it equals more cure time prior to base or top coat. 1:1:1 and base over in about an hour (or less depending on temp.). 1:1 with no reducer roughly 12-24 hours just to give the idea.
Epoxy is very versatile.
