Sorry to hijack thread, but i thought it would be easier than starting a new thread for one question,
i cant remember if its been discussed, or if ive asked, but ive got a stainless vent flap, and want to paint it, what sort of primer should i use? Isnt it etch primer? Is it available from frauds? As they do nice bih cans of alpine white which is close as god dammit to my white!!

Thanks, and sorry or the hijack

Yes etch primer, in Halfords it's Upol 8.

is that because the white bits on a D0lly IS alpine white..innit

Sean

also do i need to key the metal surface up or will etch primer be ok without keying (never painted smooth stainless before)

Etch primer contains acid which microscopically eats into metal and scuffing gives a physical grip, so why not have both? Degrease it, scuff it, then etch prime it.

ok thanks old nail, priceless informtion which i needed, thanks

shall i do it before or after crimping vent flap seal on? as id rather do it after but if the acid eats at the rubber? or either i masking tape with newspaper the rubber up to prevent it being contamintaed?

ps sorry again for hijak on thread

Do it first and let it dry hard before putting the rubber on, you can always touch up scratches later.

This is all great stuff...I dont think its a hijack....just any paint tips are great for those who are able to share info.

....Thanks to all and especially Mr Nail !
