Basecoat problems...

Well I am painting some stuff for a customer. I have used cheaper quality products and never had problems but with his stuff I am using PPG Deltron base and DCU2021 clear. I threw a few coats of SPI epoxy primer on all the pieces prior to painting.

I shot some base and it was going on dry so I let it flash and came back with a heavier coat or what I thought was heavier without being to heavy but ended up having a TON of runs. So I just called it a day and figured Id get back to it Monday.

I am going to go back over EVERYTHING with 600 and get it smooth and then spray more base over it. I know you arent supposed to sand base unless you have stuff in the paint, but have to reshoot base over it. Is it okay if your base goes on with orange peel, and then clear over it, of course I will be wetsanding and buffing the clear afterwards to get the orange peel to match factory. Will the clear amplify the orange peel in the base or will it be nonexistant if I were to get the clear completely smooth.

Also basecoat should have a matte finish to it before clearing... there shouldnt be much gloss if any correct?

If you are painting a solid color orange peel will not show, if you are shooting a metallic it will show. There should be no orange peel or runs at all with base though, you must be spraying to heavy of coats to be getting runs and to close to your panel resulting in orange peel.

I think that was my problem, I was spraying way to close resulting in peel.
The reason I got runs for the second coat is I upped the fluid way too much and with spraying so close to the panel resulted in runs. I am using a devilbiss finiahline gun that has served me well in the past. Chances are the temp had something to do with it as I was spraying in 60degree weather. I used dt885 reducer but gave at least 1 hour flash time between coats.

Should the base be flat/matte before clearing or should it have some gloss to it?

You will want to be at least 6" from the panel you are spraying. The first coat will be just a dust coat not a cover coat, dust it on, it should be fairly transparent. second coat will be a cover coat but will still be a bit transparent depending on the paint. Third coat will be a cover coat, you should not see anything through it but if it is a very transparent paint you may have to give it one more coat to be safe. If your paint is a metallic color you will want to give it a final dust coat to have the metallics stand up and be brilliant rather than drowned in a wet coat.

Good luck on Monday.

Same thing apples for your clear, stay at least 6' to 7' away from the panel. The first coat may look a bit dry but it will flow out by the time you spray your second coat. There is a fine line between not enough clear and to much resulting in runs, so if you are unsure if you have enough clear on, let it flash and have a look, it may flow out just right. If not it is way easier to put another coat on than to sand runs.

Great, thanks for all your help

Is there some science to pouring out the PPG reducers out of their gallon containers? I always seems to spill a ton. I bought a plastic piece that attaches to the top of a gallon container (paint cans) and gives you a spout to pour but with the reducers I always seem to spill a good amount.

Yes there is a trick to everything. Pour your reducer with the spout at the top, this lets the air in and the reducer can pour out steady without spilling.

DUH!

Thanks again man youve been a great help. Hopefully everything goes smoothly Monday. Glad there are forums around here that actually help people out instead of cutting them down!

No problem. There are no stupid questions, if you don't know you don't know. We all had to learn these tricks at some point, and it is my privilege to pass them on.

Figured I'd update you guys with the finished product.
A little cut and buff and they look mint. Sucks that it was cloudy as it wasnt so easy to get a good reflection shot of the stuff.
