Speed clear on large panels

[Rbm]

I'm going to paint a 22 ' camper outside under a shelter. If I clear one side at the time, can I get away with using speed clear or will it cure to fast...I expect 80 degree weather at least...a few weeks out..i just want it to be tack free as soon as possible.

I wouldn't try it. Tack time is not a whole lot faster than Universal or Euro, just through dry time. It must be double coated with none to very little flash time.

Use Euro with extra slow activator and 895. Maybe use retarder, esp, on the last coat.

Have yet to try the speed clear, but that doesn't sound like a good idea without one hell of a flood gun hooked to a pot cannister. I'd go with above advise using euro.

The hardest part of painting a large surface like that is maintaining a wet edge, so it all flows together.
You'll get overspray and dry spots everywhere.
What you want is the opposite of something that dries real fast. The slower the better.
If I do a large surface, like a bus or camper, I load up on the retarder and basically mist the paint on
until it's wet all over so it all melts together giving a even finish.

Paint it early in the morning just as the sun is coming up and you will get less dirt in it.

I do know someone used it in midwest on the side of a 44ft motor home.
If I were asked first, I would have said no way, but he did in the shade and used slow activator and said went great, I was not there to witness, but this guy is a pro, so im sure he's giving me the facts.

Seems like it could work if it's possible to paint the sides in one session, and the ends in another, maybe. But having to go all the way around would be a mess, imo.

The only issue I've had was when I was painting a booth full of small parts. The very first part I cleared had a haze by the time I got around all the parts. I'm not sure if it was overspray from the other parts or if it was from not being able to turn off the fan until all the parts were cleared.

I'm sure a professional accustomed to large items could spray the faster drying product with a large enough compressor, not too long of a high capacity hose, and the proper gun for spraying a lot of material fast. Otherwise it would just be better to play it safer. New product & extra large area is kinda like 2 strikes against you already .
If going forward with the speed clear (I would not), I would do both slowest activator & add retarder.
