Spendy but for aluminum diamond plate she bonded great.
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 Depotโs when priming my Tahoe to raptor line and that did work great in that application but for aluminum Iโd 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.. Iโm happy with that. If I were doing anything other then aluminum Iโd probably go with Home Depot as it has worked on plastic wood and everything else Iโve put it on and is half price.

Good product
Upol makes a pretty solid product. Been very satisfied with the dry time and its hardness after cure. Seems to stick like crazy. I recommend

Decent but pricey
Used this to cover bare metal and Bondo patches prior to applying raptor Berliner to the bed of my F250 Decent product but not a lot of coverage. Seems expensive for what it is. Probably would opt for Rust-O-leum primer the next time I have an auto painting project.

Compatible with Urethane Paints
I used this to prime some spots where I sanded through to metal and it never caused any weird reactions with anything I sprayed over it. I sprayed U-Pol High Build primer over this and also a regular automotive urethane base directly over it with no issues.

Probably a must if rattle can spray painting aluminium
Expensive, but I think worth it to ensure adhesion of spray paint, especially to aluminium.
