I have read in older posts around the place about applying either urethane high build or colour (in hidden areas and what not) over the top of Epotec 408 wet on wet. I've been checking the tech sheet and I can't see any mention of this. All I can see is recoat time frames from as low as 10 hours minimum.
I was advised against going wet on wet by a Protec informant over the phone, he said once cured, just sand and apply your next product over. So this is what I have been doing which is okay because my urethane high build does say "Fully cured 2 pack refinish coatings that have been degreased and sanded".
Although places like radiator support where I don't want any build, I wouldn't mind scuffing, applying more epoxy and putting colour over wet on wet.
Or say I have had to remove high build to do some more filler work on areas that weren't quite right, once I finished filling and sanding, I wouldn't mind to spray a coat of the epoxy and straight into the 3 coats of high build w/w. My 2k high build doesn't recommend being put over the top of alot of filler / bare metal without an epoxy put down first.
Can colour (like a satin black) be put over the top of well cured epoxy once scuffed, or is it recommended to cut back, coat with more then colour wet on wet?
And if wet on wet IS possible, how long must I wait to get the second product on the first?
I will appreciate any insight
