One thing you'll learn right off is everyone knows something usefull,your style and technique will evolve over the years, no one person has all the answears..what works for me might not work that well for you...So keep an open mind and always be willing to try different techniques you can add them to your own style. I learned a lot when I was traveling the east coast and working in many ,many shops..If your lucky you'll learn something new every day...I've been in this for 35 yrs and I learn new stuff every day..it keeps things interesting...

Just seems to me that this paint sinking issue makes the case for using a sealer over the car on all overs..a difference in porosity of the substrate can make a problem when trying for a first class job..

i am in the collision side of it and i seal everything i do.

not once have i ever painted directly over primer.

just the way i was taught.

very good post deadbodyman,you are 100 percent correct.i learn something new on just about every job i turn out.

Something I learned last year was spi epoxy makes the best sealer I ever used.I painted a camero I restored ground up including rear frame rails so I wanted the best.
after hearing about people using it and liking it,(really liking it).I called the owner and got his opinion...and proceedure...normally talking to the owner or a rep is a waste of time,they just want to sell you thier products..NOTthis guy hes helped me in the past using other products so I trust his opinion ...
I've been using epoxies for all my restos for well over 25 yrs on bare metal and have been using Spi exclusively for maybe five years...I never dreamed it could be used as a sealer never mind being the best sealer I've used..I was very impressed that epoxy is just amazing..it also eliminated any need for any type of building primer,for my restos...it sands AND builds ,something else I learned in the past two years of being a member here...its funny I was using it all along and when i joined HR thats when I learned just how good it really was ,I never even thought of sanding and building with it ..or calling the company, that was a first for me too.
all the years Ive used epoxies that was unheard of,you HAD to use a build primer with them...
But there are some old timers (and younger guys too)that will never believe it and never try it,they are to set in their ways and know all there is to know, I'm just glad I'm not one of them...After all these years I still cant wait to get to the shop and get going...theres always some kind of challenge waiting for me that I havent come across yet...You may master the art of bodywork and go on to master painting but No one will ever master every aspect of this work ...not ever,..It'll take me another lifetime to get bored with metal shaping ,my new challenge.

I tend to agree with the ohters on here with letting the 2K sit for a day before topcoating. I usually sand it and let it sit open for a day before topcoating it, knock on wood no problems. I can vouch for DBM on the SPI Epoxy, it is the only sandable epoxy Ive ever used and it is great as a sealer.
