I was going to use flashtac on my floor and in my doors of car for deadening. im not going to enter competitions or anything and i just want my car to sound nice without going overboard, and flashtac being cheaper and as well as me working in a hardware store, seemed like a good alternative. BUT i read that if you use flashtac on the doors, during summer on a hot day, it heats up the door, melts the flashtac and it runs down ur door.. is this true? coz of so F&%K that!! lol. pardon the language. I just dont want to spend big bucks on deadening my car if my car isnt going to be used in competitions or anything. Has anyone used flashtac and had this happen or found it to be alright?

Can't say that ever happened in my car

[sliksilvia]

it gets soft but doesnt turn into liquid and run down the car, it has to b pretty damn hot to do that /

the bitchimen material of all those products, dynamat, flashtac etc has a similar melting point, and you should be fine, i used a hot air gun and it didnt drip at around 80degrees or so...

i have flashtac on my parcel shelf, exposed to the sun day in an day out, never had a problem.

awesome. i would have thought it would have been alright. i mean it is desgined for like gutters and stuff which is constantly in the heat.

Next question. is there a HUGE difference between lets say the dynamat and the flashtac? as i said before, not a competition car, just want to deaden doors a bit. but is the dynamat worth the extra dosh? also, how much will one thing of dynamat cover? its 1mx1.5m. Is that normally enough for one door, two doors, half a door etc?

Thanks guys!

After using flashtac to do my hatch, door trims and a few smaller panels inside the car, i'll be switching to g-spot serenity or serenity max for the doors.

I dont think flashtac is that much cheaper (unless you'll only be damping a small area), and it's not the easiest stuff to work with, simply because you have to cut several thin strips rather than a single large piece.

It does seem to do a pretty good job though.

another one to look out for at your local hardware store is gripset.

its a water-based bitumen paint and it doesn't stink forever (like a lot of other non car products).

i've used it to great effect in harder to reach places.

in your doors etc, i'd just recommend some jaycar brownbread or gspot stuff. i find it hard to recommend dynamat or stinger stuff when the cheaper stuff does it the same or better (gspot)...

Awesome, thanks. Wouldn't a water based bitumen product be bad for the doors? Wouldn't it coz them to rust over time? Or are the doors actually painted on the inside as well?

Thanks for all the help guys.

water based would not be the best for door installs

look at the stuff at autobarn or bunnings its a brush-on bitumen/tar that only comes off with petrol...works well and is very cheap.

I put flastac on both doors last summer, and ill be never using that sh*t again. After a couple of weeks it started slide off. Although it sounds cheap per roll, you end up using a lot and the price adds up. If i was to do my doors again i will be using serenity max, as it is more cost effective in the long run.

yeah gripset is great stuff, but its just not a substitute for some good quality sh1t like serenity max or dmat extreme.

i'm gonna be using serenity AND gripset in my doors.

and for that matter, water based doesn't mean if it gets wet it'll wash away. gripset sets hard.

i wasn't refering to it washing away. i was referring to rust.

water-based. as opposed to oil based.

the water will evaporate (the solution will dry) and leave a hard, dry and dead film over your surface. rust is a non-issue.
