so the b/s that it doesn't matter is b/s.. as you'd skip the use of sealer and save both time and money..
anyone that says it don't matter, ask if they are spray'n a sealer coat. if they are, they were talking out their corn hole..
The only reason I spray a sealer is I always have sand throughs somewhere or another and bare metal on edges, as far as protecting one brand from another with a sealer just not true. As mentioned earlier above have sprayed different brands of primer, then a different brand of sealer, then a different brand of base and clear as well. There are a lot of guys on this forum that shoot SPI epoxy as a sealer then their own brand of base then come back with SPI clear. So the arguement is pretty much moot right there.
