Bob is right on as alway's.
That Nason clear is a nice one and the 3:1 will do great. It's not a spot or panel repair like the 4:1 so it won't dry out as quick on you. Just be SURE to use the right temp catylist for the ambient temp when you shoot it. Using the high temp when it's around 80-85 will slow it down a little more on the dry time which can be a big help on the flow out so don't be afraid to use it.If it's 75 or under,go with the next lower catylist. I think they only have 2 temp's for that clear,ask your supplier and make SURE it's for the 3:1 clear.
Lay you 2-3 initial coats of clear and color sand it out being carefull to recheck for any odd scratch patterns with a grease & wax remover or the 50/50 alc.water spray. Resand where needed to straighten it up.
Shoot your last 2-3 coats of clear,reduce each batch 10% with Nason reducer,proper temp of course,and shoot the final coat's of clear.
I have not used the Endust wipe's,just the spray on plain cheese cloth and it does work BUT,and I say BUT, Don't spray it on heavy,just dust the cloth and let it air out for 10 min. or so before LIGHTLY tacking the car off.
Or, Just drag out the chain out of the 4X4 and connect it to the BODY someplace out of the way and let it lay on the concrete.
Do the clear EARLY in the morning,like shortly after daylight,and the bug/trash factor will be at it's lowest of the day.
Take a box fan and set it up on a step ladder or such,secured of course, at the frount and set it on LOW and have a light breeze to help push out the fumes towards the open end of the carport.
