Read many of the posts on here and made a couple trial runs yesterday on some scrap material. My intent was to get the gun setup correctly and learn how to put down the minimum amount of the stuff.
Taking the advice found here about the 1:2 ratio (primer to catalyst) rather than 1:1.5 - this stuff can be challenging getting it to lay down nicely without mottling. Even at 1:2 ratio the mottling was quite bad initially.
Rather than mix up a new batch with even more catalyst (like 1:3), I had about 4 oz left in the mixing cup and so a thought occurred to me that maybe the mix could be reduced with a bit of lacquer thinner. So I added about an oz of lacquer thinner to the mix - and yes I am aware of SW statement about not using anything but the recommended catalyst.
The results were excellent. I was able to get a nice consistent light coat with the reduced mix. I tested both samples for adhesion (gorilla tape pull test & razor scraping) and cannot detect a difference in adhesion.
Curious to know if anyone has tried this and if I'm asking for trouble down the road? Lacquer thinner is a lot cheaper than the catalyst and seems to help lay down a nice light coat.
