Rocket additive?

Morning folks (in the UK anyway)
Currently at work I am finding turnaround slow because we are having another long, cold winter. Temps barely above freezing. We dont have a bake booth either.
So my question is; has anybody used rocket additive in their primers and topcoats? And what problems can it cause?
I use a fast hardener and thinner/reducer in 2k primers and usually a medium hardener and thinner/reducer in my topcoats and clear.
Will rocket affect flash times or cause die back? I dont normally have to buff jobs so I dont really want to start.
Its not something Ive ever liked the sound of but Im thinking about using it just to speed things up.
I’ve used it on and off over the years sometimes I found it worked others not prob down to different products/brands I think on some clears it gave me a bit off peel effect and I used to add a little reducer to counter it other people thought the same at the time I do know guy who uses it all the time year round he thinks its great although I’ve seen it die back a bit but that could be down to his upol clear and drying much too quickly in the warmer temps.
Glasurit do an accelerator they sell it with 923-888 clear guy was raving about it to me other week both clear and accelerator which he used in a range off products supplier was telling me that the debeer rep told him he has seen it used with one of their clears to great effect
I,d get some try it on couple small/older things first its not that expensive for rocket.
Thanks for that.
I dont mind buying it to try it, as you say its cheap. I just dont know if it could have an effect over time, customer complaining and re-work.
Cant see it affecting primers too much but its topcoat curing overnight I need to speed up really as its still quite soft the next morning.
Have used it in all the shops i’ve been at in both primer and clear. Personally not a fan, but does do the job. I only ever put a few drops, too much does cause clear to die back but can be polished up and could cause primer to go off in the gun. If you’re looking for a fast turnaround i’d invest in some infa red bake lamps. Rocket speeds up drying, but infa red lamps cure the paint, and doesn’t involve mixing products!
I’ve used one called speeder on the odd occasion not mixed it with my hardener just put a few drops in when I mix, never had a problem with it but try not use it things like that if I can help it. What I do find is when I do a full cab and use a slower activator the paint is always harder in the morning than it is when I use a fast activator if I’m doing a load of parts, even in the condition you describ e, so as daft as it may seem it maybe worth trying a slowing your hardener abit.
As you know Jack I work outside, so use this kind of additive regularly. Being judicious with it’s use is the best way. A little splash will help to speed things up no end with no real ill effects. Add too much and you’ll get plenty of die back!
The best product of this type I’ve used is DeBeer 30-69 taping additive. 3%-5% in one of their HS clears would bring bake times down to 10 minutes, air dry in an hour if you don’t need to buff it heavily.
Try out mipa re active thinner, basically much the same as racing additive or de beer taping additive, it’s a thinner that accelerates the drying and reduces potlife. Beware of accelerators and rocket in fast hardeners they’re not really recommended to go together, accelerator and fast hardener can make clear a little brittle and stone chip easier and rocket can actually retard some fast hardeners.
We used to put it into every new primer kit hardener and we noticed it slowed the drying of the primer and when we questioned upol they admitted it can retard some fast hardeners.
Try out Sherwin Williams hpp air dry primer, you’ll never believe a primer can dry so fast and I’ve yet to see it sink as long as you prep well as it’s a little bit lower build than your average primer but not as much as you think. I use a lot of this and I absolutely love it ,I can have 3 coats on and nearly dry by the time I apply 3 coats of standard primer and let them flash 10 mins between coats.
Between the air dry primer and hpc15 air dry clear I can do a bigger repair job in one day without baking or extreme heat. It costs a little more but you’ll more than save it in time and fuel bills. Main thing with the air dry clear is to really hammer it on wet with low pressure and get a good build on, if you do it that way it ‘ll stay glossy, under apply or use too high of pressure and it can drop back. See can you get a demo before buying but I think you’ll like them.
