Another Paint Question

[Vettra]

I know that paint manufacturers state that it is important to stick with the same brand throughout the project. Is that absolutley necessary? I haven't been painting long enough to develop a brand loyalty yet. Still trying out PPG, HOK...

I have used different brands throughout a paint job and had no problem, BUT, on the other hand, if you are not for sure, I would suggest being a little more specific and possibly we can help (i.e HOK sealer with PPG basecoat, and UC35 over the PPG base). I haven't sprayed some of the paint lines for quite awhile, as I'm sure they've changed througout the years. I remember the days when Dupont used to use a "basemaker" which had an additive in the reducer that helped make the clear adhere to the base....I don't think they use that anymore?!
I've sprayed Sikkens, Glasurit, Dupont, HOK, PPG, Alsa...and some can be used under/over others, and some cannot
I still like the HOK and PPG, but I know alot of other painters like Dupont.

In my experience some things are always safe. Any 2K urethane or polyester primer can be used under any base for instance. Any urethane clear can be used on any polyester or waterborne base. If anyone has experience to the contrary, I'd like to hear about it. I've put Glasurit and Limco clears over R-M, PPG and DuPont bases with never a problem.

The classic horror stories of old were from painters mixing enamels and laquers which have totally different characteristics.

should not have a problem with multiple brands..hell i shot a blazer for SEMA 'bout three months ago and used Dupont 4904 primer, sealed it Dupont, based it with Matrix EFX and cleared it with Sherwin Williams 950 clear!! yes, I said Sherwin Williams. I thought they only did house paints...that was until I started working for my current bodyshop now for 3 years.
