The temp meter - are you just talking about an IR thermometer? I do have one of those if so.
I don't really care to do the pinking or anything fancy, unless it's recommended for durability. I'm not trying to get any more scale than it's an airplane and it's painted Cub yellow.
I don't think the UV protection would be necessary because it's not like it's going to sit out in the sun day after day.
I work in the aviation industry and my coworker uses Stits on his full sized planes and he said the UV layer shouldn't be necessary. He told me just just poly-taks, then poly brush the first layer of dope on, then sprays two more layers after that.
I will be working it in my garage with ample ventilation.
