Which Primer Is Best To Use

[SurGie 54]

Hi Members,

 

I shall soon be sorting out the projects welding and would like to know people's opinions on these items im thinking of using for my welds and the clean strengthening steel plates.

 

I was going to use some of that red Jenolite primer but it looks like hammerite have bought them out and are no longer available.

 

1ST Primer

 

2ND Primer

 

3RD Primer

 

I'm thinking of using the same or similar red primer like what was used on Dr Sarty's Evo project.

 

Cheers .

Bilt Hamber stuff is very good, my brother used it on his 306 recently, for your use there's the following products;

 

Zinc primer;

use a good etch primer followed by a good two pack primer

Bilt Hamber again here.

 

Not used anything else out of a can that's decent to weld through, has good adhesion and sensibly priced.

Great thanks, Bilt Hamber it is then.

DO NOT try and weld through primer, you will never get a decent weld out of it! You can use it to paint the back of the metal before you weld it but that's only good if you're putting in a new patch, and it can still affect the weld quality.

 

You need to be welding to BARE METAL , ideally on both sides of the material. Do your welding, then use an etch primer (U-Pol is good) to coat the bare metal but try to avoid any existing paintwork.
