Q. How much does
it cost? That is usually the first question I get after the
introduction.
A. The answer to that
question is predicated on many things on your vehicle or parts. I
base my prices on the size of the vehicle, assembled or
disassembled, multi-layers of material build up & what the base
material consists of whether it is sheet metal, aluminum, Fiberglas
or composite. How much of the surface area is also a
factor. As a paint & body repair specialist, I do other things
beside blast off paint. I take many things into consideration before
pricing. So seeing & discussing is part of the pricing process
for me. Other people in the business do it differently most of the
time. The ones that will give a one-price-all are not doing
what I do. They don't have background experience as I do
so there lies the difference in the prices you will get when you
call other operations. Like calling Maaco & a Lexus dealer
for painting. Just different pricing levels for the quality of
product, along with the service that you get for what you are trying
to accomplish.
Q. Do I have to
remove the glass & chrome?
A. No, it is not
necessary to remove the glass & chrome. The plastic media is not
aggressive enough to harm glass & heavy chrome. The media is
harder than most acrylic paints & softer than the metal. The
plastic lenses along with lead, potmetal & soft chrome will pit
it not protected or removed. Emblems and soft ID badges will also
pit. I do recommend removing the glass & handles to get a lot
better strip job. Everything is exposed if it is disassembled &
therefore will save the time to come back & either sand around
or remove it later. All the inner mechanisms usually have oil &
grease on them & will build up with the dust from blasting along
with some of the plastic grit. Therefore, I would rather do it with
the inner mechanical removed but either way will work depending
on what you are wanting to accomplish.
Q. Can I just
blast the outside, my jambs are in real good shape?
A. Yes, the outside can
be blasted only. If color changing, I recommend doing the jambs too
as to not have any incompatibility problems when you go back over
them with new & improved materials we have today, especially if
it hasn't been painted by a reputable shop in the last few years.
OEM Paint from the 30's-90's are not as durable as what is on the
market today so it is better to do the jambs. Always a choice for
the vehicle owner to make. If I am to do the restoration, I will
strip the complete vehicle to avoid down the road problems that
arise in the process. Also most reliable shops will not even give a
ballpark price on a resto without seeing the vehicle completely
stripped. On the other hand the jambs are a matter of
choice if you are wanting to cut corners to save funds.
Q. How long does
it take?
A. Some shops that are
blasting will give you one day service. Most of the vehicles I do
for people will need to be prepared for the stripping process. If I
have to build brackets to be able to use the rotiserre then it is
longer. I have rarely been able to blast a vehicle in an 8 hr. day
due to layers of paint, bondo, taping jambs for protection for
outside only blast, & doing steam cleaning underneath to remove
grease & road grime before blasting to eliminate contamination
of the blast media. It has to remain as pure as possible to insure
that the next vehicle will not leave with a coat of grease or oil on
the metal surface. Every shop that does Plastic media Blasting has
to recycle the media numerous times to make it cost effective to
operate. The media product is pricey compared to silica, black
beauty, aluminum oxide etc.
Q. Do I have to
get primer or sealer on the surface as soon as you are
done?
A. Not necessarily. If
the vehicle has not had the zinc phosphate coating that was on the
vehicle from the factory removed by grinding or heavy sanding, then
the surface will hold up very well in a garage or shop for quite a
long time. The only things that need to be treated are areas where
bondo was removed or the areas that have been ground. Of course it
is always to your advantage to get the surface sealed to prevent
oxidation as soon as possible. Some people have heavy acid content
in the system, then if they handle the metal or touch it, the
surface will show a hand mark within a couple of hours. Otherwise, I
have had vehicles in my shop for months to years without sealing or
having an oxidation problem. I also offer this service in house for
a fee.
Q.Why not
just sand blast it to make sure I get all the rust
off?
A.
Just because you can not see the surface rust does not mean it is
gone from the lower levels of the metal. Without doing a microscopic
test to see if there is anything smaller than can be detected by the
human eye. I always recommend treating after sand blasting. Plastic
media will only remove the light surface rust areas & stains at
the most. Plastic media is a paint removal product, it does not
remove metal as the other blasting procedures do. Plastic, unlike
sand, aluminum oxide or any other grit products is propelled with
20-30 psi instead of the 90-110 of the other products. Therefore the
grit is what removes the paint not the force of the impact. A few
people mix up the term bead & grit. Plastic is a grit cut
product that works with edges of the grit to do the stripping.
Beads are just that, small round beads that have to pulverize to cut
what needs to be removed, therefore more force is needed to do
removal process. Thus the heat transfer is a problem on some sheet
metal, can cause warping.
Q. Will there be
any warping on my vehicle?
A. With plastic grit,
there is not heat transfer to the base metal. The low blast pressure
& the shape of the grit remove the paint fairly easily & a
layer at a time in most cases. The strip rate on every vehicle is
different.
Q. Can you do
Fiberglas & will it pit it bad?
A. A lot of variables
are present again. As I said in earlier question/answers above, that
all the surfaces will strip differently. Fiberglas cars vary through
the years with different types of substrates. Late 50's to early
60's are mainly Fiberglas resin layups with mat or cloth laid under
for the strength. Mid 60's & up have more of a real thin layer
of epoxy type gel coat with a composite substrate for the strength.
Depending on how long the vehicle sat in the sun through the years
plays a major role in the integrity of the substrate when it is
stripped. Some absorb & integrate the paint into the
gelcoat/epoxy & are difficult to get just the paint removed
without light pitting of the fiberglas. Sometimes 3-4 paint jobs are
stripped off of one vehicle & then the original has UV damage
hidden underneath with the OEM paint that is still on the car.
Removing with some pitting can be expected but can be surfaced with
file board & 40 grit paper & redone with 80 grit to smooth.
All surfaces will have to be flattened with resurfacer & blocked
to achieve the desired results. No different than if you take the
paint off with a grinder or sander. Aircraft chemical stripper is
another alternative but is extremely time & labor intensive
& doesn't do as good a job as Plastic media blasting. The cracks
& crevices take a long time to clean out with this
method. Not to count the hazardous issues when using it, plus
the softening of the get coat if used too extensively.
Q. Can you blast
aluminum?
A. The answer again is
yes. The different types of plastic grit can be used from the size
of baking soda to the grit a little smaller than kitty litter. The
desired results can be achieved with the smaller a majority of the
time. Aluminum comes out with the best results over sheetmetal &
Fiberglas. It has to be done with TLC just like the fiberglass but
the results are very surprising to most. Vehicles & aircraft
types of aluminum will come extremely clean without warping. Most
aircraft manufacture facilities use this process to strip in house
projects & for cleanup. Bell helicopter is a prime example. They
use this method extensively.
Q. Can I do it in
stages or pieces while I work on other parts of my
project?
A. Yes, I will blast
parts, assembled or disassembled along with helping with disassemble
for a nominal charge. Can do parts first & body later,
etc.
Q. How long have
you been doing the blasting?
A. I have been doing the
blasting for 2 years now but have been working around it by using
the Plastic media blasting process for over 20 years. Plastic media
has been around that long but has been used mainly by aircraft
industry due to cost factors.
Q. Do you pick up
& deliver?
A. Yes for pick up & delivery charge
depending on distance. |
