UV primers and lights

I remember Jimmo posting a thread about UV primers. I don’t have the Diamont stuff near by, but I have a PPG shop here. anybody used the P110-5000 from PPG? dry in 2 minutes! sounds pretty killer to me.
what do you use for UV lights? I imagine this being a much bigger pain for restoration jobs with lots of primer – you’d have to move the light every 2 minutes around the car. still probably faster than urethane dry times.
I’ve found a number of different heat lamps for baking traditional solvent clears and whatever else. They say water based paints cure in less than 6 minutes…. which has me thinking.
How do water based primer compare to UV in price and build thickness? And what are EPA regulations like? I don’t have a booth, so everything I do is illegal….. what are the rules on water based products?
yes that uv cures in a couple minutes with a uv lamp but imo uv primer is best for small areas no bigger then a soft ball
what kind of light do you use?
and does UV have any issues with compatibility? does it have to be sealed before base?
UV primer doesn’t really have any compatibility problems I’m aware of. It’s not used for larger jobs mostly because of the cost, it is great primer and sands/builds well. I know Leno used it on his Eco-Jet..lol. You would need a large lamp to cure it all or just toss it out in the sun for a while. The water-based primers are not forgiving like urethane and will crack if you try and build them too much, I wouldn’t really use them over large area’s of filler.
but you definitely think it’s worth it for the repair shop? the cost of primer per use and up front cost of a light must save you quite a bit of time.
In a repair shop its great for small jobs, I know thats how BASF markets it. It costs more but the time savings = more $$$…. Depends on how the shop operates, it can be worth it for some places……great for that 5 o’clock F*** up! lol
Also the waterborne regulations I would imagine are similar to solvent, they still contain some so either way your not likely to comply.
if u aren’t on a time frame with each job then i would much rather use a urethane primer everything is “spose” to be compatible i seal everything when spraying.. it was at shop when i started working there and is nice if have a small issue and are ready to go in the booth.. but it gets used once a month maybe…
water based primers are more designed for bumpers imo.. thats what the shoot on rebuilt bumpers have used some on some bumpers and has worked well and sands great. but like jimmo said can’t put it on heavy or it will crack
I have used UV primer in several shops. The PPG product is excellent. Very expensive, and so is the lamp. Only really use it on small jobs where speed is a huge factor. Most are sold in aerosol cans for the convenience/speed of small repairs.
Water primer has very limited use and is generally hard to come by since few places use it.
All in all 2k urethane is the best all around primer and is very cost effective. Many products are available, and can be very inexpensive in the cheaper brands.
is there really a reason to go with a top dollar light? seems like UV lamps (grow lights/reptile lights) could work….. hmm
how do the rattle cans spray? I mentioned the stuff to the local shop and the owner was very intrigued, but I didn’t know if it was worth the investment or not.
how high of production do you need to be doing to merit a uv setup? what does a good lamp cost?

The spray cans spray perfectly fine. The product builds well and from everything I’ve done 1-3 coats will suffice.
I wouldn’t experiment with lamps too much, I am sure there is only a certain spectrum that will cure the primer.
The better lamps have nice stands which make it easy to use.
How much production merits the cost? That depends on the size of jobs and preference. I would never spend the cost for doing it at home or on a small production scale. But if I owned a collision shop of any size I would buy one when ever I could afford it 😆
