Simply SP-024 Grey Etching Primer for Cars & Motorbikes – Fast Drying – For Treated & Untreated Wood, Metal, Aluminium, Glass, Stone & Various Plastics – 500 ml

I'm using this on cleaned up steel for cap body panels and it sticks pretty well actually. Having tried to wire wheel some off it took a decent amount of effort to get it off which means it's staying on pretty well. OK price too. Will be my go to primer from now on.

very very good for an aerosol. Excellent

Worked extremely well providing a prime coat on bare aluminium that allowed an ordinary primer and top coat to adhere to the metal perfectly. You don't need much to get good coverage and the tin was enough to do two bicycles frames and all the finishing kit (bars, stem, seatpost).Would recommend.

Very strong odour, needs to be used in a well ventilated place, or outdoors. Doesn't really need much sanding after spraying bare aluminium bike frame.

I bought this because I'm currently custom painting a whole pc case and using this as the base coat primer for all parts of the case, even the plastic bevel around the front. It works brilliantly and becomes scratch resistant after 24 hrs curing.

Used to prime my trailer wheels before painting, also used on my boats stern drive unit. Good spray pattern, fast drying.Very pleased with the results.

Does what it says on the tin. Well worth the money

easy application, and as long as you shake thoroughly this can goes a long way giving great coverage.
