Retarded old fart go back to your ding repairs and leave this place forever.
What? And leave it to your misinformed and bad advice? Not likely amigo.
That which can be assorted without evidence was read in an illegal magazine.
I've never taken a hotcoat outside and then back inside. I've always waited 5 minutes after brushing it out. Never had a problem. To each his own. That's what has always worked for me.
Depends on whether or not there is any UV light getting "inside". Might even depend on what bulbs or light source you use. Letting it sit inside is a gamble. Plenty of info confirming this on YouTube, SolarRez etc. What the hell? Do it any way you want. I don't have to sand it, so makes no diff to me.
Got a link to said info? Been doing it this way for at least a decade. Never once had a problem. I've done UV Gloss resin the same way.
Surf Source YouTube video on SolarRez. Which is nothing more than Silmar 249 with UV powder. Since we're talking decades; I first bought UV Polyester from Fiberglass Hawaii in 1998. Bought in Fives premixed, just like they sell it these days. Was told to do it the way I described in this thread and other threads on this site in years past. So by my calculation I've been using the $#!t for about 23 years. Of all the manufacturers, backyarders and one off board builders I have met, I have never heard one of them lay off a hotcoat and then leave it in the shade without first exposing it to UV for ten seconds. When I lived in Pismo Beach, there were lots of mid morning overcast days. Never had a problem as long as there was SOME UV. Clyde Beatty used UV in Santa Barbara at his factory and did the exact same way I do. I don't know the circumstance you are working with, but I'll pass on trying it your way. I'll go with the method surfteach and most people use. I always smile when guys say they've been doing something for a decade or years.
Whatever works for you. For what its worth you can see the wax start rising to the top as soon as you finish brushing it out.
The only context I'm aware of where best practice is to go in and out of the sun is when firing off your resin in intense sunlight. In this context it is it is done so as to slow the curing process.
Strangely, I went to surfsourse.net and the only video I found that made any mention of this topic said to do it the way I describe. If you have a specific link from surfsource or elsewhere you'd like to share please copy and paste it into a post. I'm open to other methods but without a link I'm starting to think you're full of hot air. I'm happy to be wrong mind you but would like to see some specific proof of claim.

Solarez which is a coompetitor to Surfsource SunCure UV resin has videos as well and their video on hotcoating also shows the method that I described.

Like I said, if you have a specific link you'd like to share with the group simply right click on your link and select "Copy" then come to your reply on this webside and press "Ctrl V" to paste the link into your post.
You're the expert. Like I said I don't have to sand 'em. That's you're duty. I'm sure you have a unique method of doing that as well.
No you're the expert buddy. You're the one who felt the need to act like you're the all knowing one and had to tell experienced builders that they don't know what the F they are talking about. Post me a link to anything on the web that tells you not to wait to let the wax rise to the top and that best practice is to as you said "brush on the hot coat and then immediately exspose the board to UV". You're the one who made the claim, and I quote: "Plenty of info confirming this on YouTube, SolarRez etc". Put up or shut up. I'll wait patiently.
Like I said you do it your way, I'll do it the way I've done it since the 90's with never a tacky hotcoat. I've never had to look it up because I have never had a bad result. Always did the way I was instructed to do it with good results . Asking me to link something is like asking BillT to post pics. The Solar Rez video was found by accident and viewed once. You go ahead do it you way. You're welcome to taking it personal. That's your thing not mine. Funny. There doesn't appear to be any artificial light in the SolarRez shop. All UV tarps with gaps etc.
