Ok so i got my some sludge on my trunk yesterday and now im wondering if it'd be safe to put some damplifier over it now or what? its dry to the touch...

apply to a clean dry surface.
note: clean

depends on how think and how long it has been sitting. i probaly would of put the mat down then the sludge.

sludge? elighten me

http://www.secondskinaudio.com < sludge is a sound deadener paste... they also make a product called spectrum, its the same thing with out the filler

anyway, secondskin says that you can apply damplifier over the sludge/spectrum... i wish it was sandable, i kinda slopped it on. but the difference from using sludge (i had dynamat extreme on it before ) is fuckin amazing.i swear to god its louder and i hear some lower frequencies better, and most importantly to me, i finally got rid of this retarded, high pitched rattle... now the rattle is less embarassing.i want to put some damplifier over the sludge because the sludge is pretty ugly

whats the advantages/disadvantages to using the spray vs. sludge on doors
don't mean to hijack the thread, but odviously you three have experience/know about this stuff

the sludge is the same thing as the spray (spectrum), its just got filler (According to anthony from Second Skin). The sludge is easy to apply, but its not the best lookign stuff thats for sure.

any dealers on this forum, holla

second skin is fairly cheap. if you order by phone, ask for the forum member discount or if you order online (if thats avail yet), find the promotional code on their forums and use that to get 10-15% off your order.... i got my gallon of sludge and 10sqft of damplifier for $80 to my door...looks like i may need more sludge in the future though.

i think im the only dealer on here for them but they give good discounts direct.
