U-Pol Products 0741V Gray ACID#8 Etch Primer - 450ml

Tiene una buena base cuando la aplicas la verdad, muy buena calidad

Works great on diamond plate, before I raptor lined my homemade camper trailer you can really cratch at the primer once dried and it seems to really get a good bite to the aluminum. I did run out of cans and opted to buy a can of home depots self etching auto primer and you for sure would have to rough up and clean the surface as that does not at all self etch compared to this (speaking about alm diamond plate, I did use Home Depot’s when priming my Tahoe to raptor line and that did work great in that application but for aluminum I’d go with this.) but I was on a time frame but all in all seems to be a 5 star item tad pricey but if it works and I only have to do it once.. I’m happy with that. If I were doing anything other then aluminum I’d probably go with Home Depot as it has worked on plastic wood and everything else I’ve put it on and is half price.

Very good undercoat for my alloy trailerVery happy

Holds paint to bare metal great only thing is i found for 10.00 less down the street at Au tozone . Amazon is way too expensive for everything im finding . In the end i saved 30.00 on 3 more cans and didn't need to wait half a week while it was shipped all over the world.

Perfect for an aluminium threshold trim prior to painting with a top coat.
