Hi John,
2:1:1 was from the UC35 page in their manual. Pg. 30. Wonder if something has changed.
I am going to stain my daughter's guitar top a light candy red with transtint, sand it back (quilted maple) , stain it yellow, and then I was going to go clear, do a kandy red burst with an airbrush, then clear coat over everything. The back is Mahogany, so I was planning to pore fill it with epoxy, sand to the wood, seal with dewaxed shellac and scuff it to 400 grit or so before I spray it.
"best laid plans of mice and men" . . . lots of places to mess this up!
The HOK manual says 2-3 medium wet coats, and I assumed that was per session.
Then let it cure at least 24 hours, scuff it, and do the next session of clear coating ?
I have no idea how long it'll take between the 2-3 coats but will talk to Coast about which RU and KU to buy and the timing/string test part.
I just wanted to see how much I'd need, because the stuff is pricey, but it sounds like I could mix 3 ounces, spray 2 guitars, and then rinse the gun and mix another 3 ounces, then shoot a second coat on both, and so on. So that Quart of UC35 should be enough to do 1 or 2 electrics. 3 rattle can's of pre-cat cost me $25, so the cost isn't really that bad since I'll have the tools.
You said if I wanted the wood to show, that you'd clear, then spray the candy, then clear again. Would you use UC35 for that first clear coat, or the SG100?
(Edit: I called Coast, they had me call HOK. Thought the SG100 would cause the dye to bleed. Neither coast nor HOK had any experience putting SG100 or UC35 over shellac, but the tech guy at HOK said he'd go UC35, wait 2 days, flat it with 800grit, then do the burst with SG100. UC35 an hour later. Great people at Coast and HOK. Easy to reach and helpful even for a guy like me spraying a couple of small projects a year)
Thanks,
Todd
