This was not the first time I've used this brand of self-etching primer. I bought a second can because I had such good results with the first when painting an aluminium sheet a few months ago. Same this time too with another aluminium surface. However the spray nozzle has either been redesigned or had some sort of issue because off centre I definitely had more 'blobbing'. I'm sure that is not the right term but what I mean is rather than the fine, even spray I had a noticeable number of larger droplets fall on the outer edges of the spray area. The item being painted was coated smoothly but the protective wooden background board it was propped up against had a number of these larger blobs each side of the object.. With more absorbent surfaces, like wood they'd be covered up by a second coat and there would be no issue. But with any metal surfaces it needs perfect evenness each time for a good, smooth finish. The conditions, all the preparation and spraying instructions were followed precisely. The nozzle was cleaned between each of the two coats but I still had the same thing the second time too. Maybe it was my spraying technique but I was left thinking that maybe the spray nozzle was to blame. Read full review

Don't be worried about the price, it's good primer + it's 500ml not the higher priced 400ml option - I'll say that I gone through 4 cans in one day all the paint in the can was ran out fully & still the can had lots of pressure left in ready to go. It coats nice & dries to a dry Lt/medium grey when wet a vry dark near black colour - fully dry 3 hours in 9 degree temps. Though I wish I could get etch white primer in the same brand...... maybe a not far price that would be wonderful.

A very good product. It does what I want it to, I providing a secure base coat key for successive paint coats. Quantity for price, it is good value. I use it for diecast modelling. I can use it with other paint brands & get no anti reaction

An effective propellant until its emptied. Excellent adhesion, and a quality flat mid grey finish, which covers very well. Especially good used on certain alloy parts etc.

Normally used to prepare aluminium, it has been discovered to be an effective rust killer and underseal on steel. Upol is the best brand as multiple coats quickly build up a measurable thickness, looks good under a vehicle and doesn't need overcoating.

i sprayed a piece of 8mm aluminium plate, left it for a couple of hours to dry in the sun , then tried to scratch it off with a thumbnail -- it didn,t scratch and it formed a smooth, satin type of finish which is ideal from my point of view -- the stern - frame on a large model tug ( 56")

This is THE ONE TO GET, the Upol etch primer is the best that I have ever used. The tin is larger than most and also the pressure along with an excellent nozzle give a constant flow. For best results plate the can in warm water before use, 5mins helps thin it then whilst the paint warms warm the surface your spraying, I have a drying lamp but you could use a hairdryer. Then spray, great adhesion and results. Hope this helped?give a thumbs up!

etch primer is essential to prepare new surfaces for the primer and following colour coats and this works perfectly leaving a secure and smooth surface

Easy to apply, can spray directly to galvanised metal as well as aluminium. Good size of can, gives a key for the top finish coat. I will buy this primer again.

I have tried the spray primers from accessories shops and the 1.99 bargain shop sprays and nothing compares to this make. Coverage is excellent, no splutters, no spitting, good to the last remains. Fast drying and due to depth of paint flat backs well. Wouldn’t buy anything else
