My first ever attempt at a light restoration

[blaze_the_6]

Well guys, my range of Bilt Hamber products arrived today and I have a couple of questions.

The deox gel instructions say that the product must be washed off after a few hours, but I have seen many people on here claim to leave it on their cars for roughly 24 hours and seal in with cling film.

I believe in following manufacturer instructions but seeing enthuisiasts do the 24 hour stint makes me wonder what to do.

My second question is, I am using Bilt Hamber Electrox is a primer as stated earlier. I am still slightly confused as to if I can paint over original paintwork or strip the paint off the entire bay as I hoped to key it and paint over it.

Basically, the only parts of the engine bay that im attempting to return to bare metal is the rust patches, but the instructions state that the Electrox must be applied to clean steel.

If it helps my case in any way, my second coating will be 2k epoxy mastic.

Thanks peeps
