Hallo all, been a while

Quick question, can anyone recommend a good underbody stonechip/sealer/similar that can be overpainted nicely with top coat? I was thinking of any old stonechip, but would prefer a smooth finish if possible? Not sure if POR 15 can be successfully over painted, but from memory it's absolutely brilliant?

It's for a new project that isn't particularly 'locostbuilders' as such, but I've been out of the scene for a couple of years and aware that things might have moved on since I had my finger in the game

Ta, Rich.

POR15 can be over painted , certainly with Hardnose paint from Frost's. My chassis has been done for 6 years since stripping off the crap powder coating and is as good as the day I painted it

Thanks Mel, you're a star Does it finish nice and smooth brushed on, and would I need to etch prep bare metal before application? I know that it is recommended, but I am tight

I was thinking of finding out who did powder coating for Luego and getting that done there - just in case I get bored in a couple of months time with a pocket full of wire brush wheels going spare....but thought better of it

I did mine with hempathane. Its used on oil rigs boats and other extreme marine places..

Been on 2 years now and still looks brand new.

Dries to a pretty smooth finish even when brush painted . Didn't need to etch prime but was prepared as Frost's instructions , one of the items I used was Metal Ready? I gave my chassis 2 coats of POR15 the first was silver followed by brown (easy to see which parts had been done) then top coated with Hardnose which is available in several colours . All done in a lock up in cold weather using a propane heater so less than perfect conditions but still a good finish, infinetly better than Luego's powder coating

What are you building now? Mel

IIRC Frost's also list a sealer? to cover POR15 before top coating with any other paint?

I used por15 marine clean, metal ready and 2 coats of (what was called) chassis black on wishbones and rusty mirrors
using a brush.
It is a very smooth rock hard finish.

POR15 is supposed to be the best there is, but I have also heard that its a bit of a pain to get the surface prep right, particularly on good bare metal rather than on rust pitted surfaces. If you don't get the prep right, it can come off in sheets like a badly applied powder coat. Paint it onto a rust pitted surface and you will never ever get it off again though.

I've used it for quite a few small parts in my MG TC restoration, but I've decided to go for several coats of spray on Eastwood Extreme Chassis Black for the chassis itself as messing around with the metal prep on that scale didn't appeal based on my experience with the small parts.

Rust Bullet is a very good paint, better than POR15 as it sticks to all surfaces.
Can be overpainted with anything, but you must overcoat within 24hours iirc of last coat of Rust Bullet, it can still be oover coated after this time but they say you must key the surface which is nearly impossible as the Rust Bullet dries so hard!
